Answer:

Factor to this equation out, the easiest way is to solve for the two x values that add up to -1 but when multiplied is equal to -6. It should look like this: (x +- ?)(x +- ?).

The factored out form is then (x - 3)(x +2), because -3 + 2 = -1 and when multiplied together gives -6.

x - 3 = 0

x = 3

x + 2 = 0

x = -2

The two solutions are therefore, x = 3 and x = -2.

Answer:

B.  2x² + x² + x = 30

D.  9x + 3x² = 14 + x - 1

Step-by-step explanation:

2x² + x² + x = 30

simplify

3x² + x - 30 = 0

x can be solve using quadratic equations

x = 3    and x = -10/3

so the answer is B

9x + 3x² = 14 + x - 1

simplify

3x² + 8x - 13 =0

x can be solve using quadratic equations

so the answer is D

Note: options A and C do not qualify for quadratic equation

The solution is Option B , Option D.

The set of quadratic equations are 2x² + x² + x = 30 and 9x + 3x² = 14 + x -1

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

a)

2x² + x² + x = 30   be equation (1)

On simplifying the equation , we get

3x² + x = 30

Subtracting 30 on both sides of the equation , we get

3x² + x - 30 = 0

Now , on factorizing the equation , we get

x = 3 and x = -10/3

b)

9x + 3x² = 14 + x -1   be equation (1)

On simplifying the equation , we get

Subtracting x on both sides of the equation , we get

3x² + 8x = 13

Subtracting 13 on both sides of the equation , we get

3x² + 8x - 13 = 0

Now , on factorizing the equation , we get

x = ( -4/3 ) ± ( √55/3 )

Hence ,

The quadratic equations are 2x² + x² + x = 30 and 9x + 3x² = 14 + x -1

Answer:

1,249 cm or 12.49

Whichever one it asks for

Step-by-step explanation:

First, we need to convert all of the m to cm.

4.04 m = 404 cm

1.6 m = 160 cm

2.87 m = 287 cm

Next, add them all up.

325 + 404 + 73 + 160 + 287 =

1,249 cm

If it asks to convert to m again, then the answer would be 12.49 m

Hope this helps!!!

Answer:

1,249 cm (or) 12.49 m

Step-by-step explanation:

1m = 100cm

4.04m = 404cm

1.6m = 160 cm

2.87m = 287 cm

So, 325 + 404 + 73 + 160 + 287 = 1,249 cm

If u want the answer in meters, [tex]\frac{1249}{100}[/tex]

Answer:

w = -100

Step-by-step explanation:

Step 1: Write out equation

166 = -w + 66

Step 2: Subtract 66 on both sides

100 = -w

Step 3: Divide both sides by -1

w = -100

Answer:

w=-100

Step-by-step explanation:

We are given the equation:

166= -w +66

To solve for x, we must get x by itself on one side of the equation.

66 is being added to -w. The inverse of addition is subtraction. Subtract 66 from both sides of the equation.

166-66= -w+66-66

166-66= -w

100= -w

-1 and w are being multiplied. The invers of multiplication is division. Divide both sides of the equation by -1.

100/-1= -w/-1

100/-1=w

-100=w

Let's check our solution. Plug -100 in for w.

166= -w+66

166= -(-100)+66

166=100+66

166=166

The statement above is true, so we know our solution is correct.

The solution to 166= -w+66 is w= -100

Step-by-step explanation:

It can be helpful to understand what the square of a binomial looks like:

  (a +b)² = a² +2ab +b²

The middle term on the right is twice the product of the terms in the original binomial on the left.

Here, we want to use this relationship to find "b" when we're given "2ab". We recognize that "b" is half the coefficient of "a" in 2ab.

Choosing a value for b² to turn the sum (a² +2ab) into the trinomial (a² +2ab +b²) is called "completing the square" because that trinomial can now be written as the square (a+b)².

Given

  x² +y² +6x -8y -25 = 0

Regrouping, we have ...

 C.No, because each lime will cost a bit more than 30¢, so 4 limes will cost a bit more than $1.20.Step-by-step explanation:

The unit price of the 8 limes is $0.25 per lime.

The given expression:

The selling price for 8 limes = $2.00

To find:

The unit price of the lime is calculated by dividing the total selling price by the total number of limes purchased.

[tex]unit \ price = \frac{total \ amount \ paid \ for \ 8 \ limes }{8 \ limes } \\\\unit \ price =\frac{\$ \ 2}{8 \ limes } \\\\unit \ price = (\frac{1}{4} ) \frac{\$}{lime} \\\\unit \ price = \$0.25 \ per \ lime[/tex]

Thus, the unit price of the 8 limes is $0.25 per lime.

The confidence interval = (7.8 , 8.0)

Step-by-step explanation:

Confidence Interval formula =

Mean ± z × Standard deviation/√n

Mean = 7.9

Standard deviation = 0.9

n = number of samples = 164

z = z score of an 80% confidence interval = 1.282

Confidence Interval = 7.9 ± 1.282 × 0.9/√164

= 7.9 ± 0.0900966432

Confidence Interval

= 7.9 - 0.0900966432

= 7.8099033568

Approximately to 1 decimal place = 7.8

7.9 + 0.0900966432

Answer:

1) [tex]50=2(x+5)+2(x)[/tex]

2) [tex]x=10[/tex]

3) [tex]15\text{ units}[/tex]

Step-by-step explanation:

So we know that the perimeter of the rectangle is 50.

The formula for the perimeter of a rectangle is given by:

[tex]P=2l+2w[/tex]

Where l is the length and w is the width.

The length is (x+5) and the width is (x).

Thus, substitute (x+5) for l and (x) for w. Also substitute 50 for P. Therefore:

[tex]50=2(x+5)+2(x)[/tex]

And that's our equation.

To solve, first distribute:

[tex]50=2x+10+2x[/tex]

Combine like terms:

[tex]50=4x+10[/tex]

Subtract 10 from both sides:

[tex]40=4x[/tex]

Divide everything by 4:

[tex]x=10[/tex]

So, the value of x is 10.

The length is the longer side. Thus, it is (x+5).

We now know that x is 10, substitute:

[tex]x+5\\=(10)+5\\=15[/tex]

So, the length is 15 units.

Answer:

Below

Step-by-step explanation:

The perimeter of a rectangle is the sum of its 4 sides.

Let P be the perimeter

● P = x + (x+5) + x + (x+5)

● P = x+x+x+x+5+5

The perimeter is 50 units

● 50 = 4x +10

So this the equation that would model how to find x.

Let's solve it

● 4x + 10 = 50

Substract 10 from both sides

● 4x + 10 - 10 = 50-10

● 4x = 40

Divide both sides by 4

● 4x/4 = 40/4

● x = 10

■■■■■■■■■■■■■■■■■■■■■■■■■■

Let's find the length.

The length is x+5

Replace x by 10 to find the value of the length.

● 10 + 5 = 15

So the length is 15 units

Answer:

It means [tex]\sum_{n=1}^\inf} = \frac{7n^2-4n+3}{12+2n^6}[/tex] also converges.

Step-by-step explanation:

The actual Series is::

[tex]\sum_{n=1}^\inf} = \frac{7n^2-4n+3}{12+2n^6}[/tex]

The method we are going to use is comparison method:

According to comparison method, we have:

[tex]\sum_{n=1}^{inf}a_n\ \ \ \ \ \ \ \ \sum_{n=1}^{inf}b_n[/tex]

If series one converges, the second converges and if second diverges series, one diverges

Now Simplify the given series:

Taking"n^2"common from numerator and "n^6"from denominator.

[tex]=\frac{n^2[7-\frac{4}{n}+\frac{3}{n^2}]}{n^6[\frac{12}{n^6}+2]} \\\\=\frac{[7-\frac{4}{n}+\frac{3}{n^2}]}{n^4[\frac{12}{n^6}+2]}[/tex]

[tex]\sum_{n=1}^{inf}a_n=\sum_{n=1}^{inf}\frac{[7-\frac{4}{n}+\frac{3}{n^2}]}{[\frac{12}{n^6}+2]}\ \ \ \ \ \ \ \ \sum_{n=1}^{inf}b_n=\sum_{n=1}^{inf} \frac{1}{n^4}[/tex]

Now:

[tex]\sum_{n=1}^{inf}a_n=\sum_{n=1}^{inf}\frac{[7-\frac{4}{n}+\frac{3}{n^2}]}{[\frac{12}{n^6}+2]}\\ \\\lim_{n \to \infty} a_n = \lim_{n \to \infty} \frac{[7-\frac{4}{n}+\frac{3}{n^2}]}{[\frac{12}{n^6}+2]}\\=\frac{7-\frac{4}{inf}+\frac{3}{inf}}{\frac{12}{inf}+2}\\\\=\frac{7}{2}[/tex]

So a_n is finite, so it converges.

Similarly b_n converges according to p-test.

P-test:

General form:

[tex]\sum_{n=1}^{inf}\frac{1}{n^p}[/tex]

if p>1 then series converges. In oue case we have:

[tex]\sum_{n=1}^{inf}b_n=\frac{1}{n^4}[/tex]

p=4 >1, so b_n also converges.

According to comparison test if both series converges, the final series also converges.

It means [tex]\sum_{n=1}^\inf} = \frac{7n^2-4n+3}{12+2n^6}[/tex] also converges.
