What 8?

There is no 8 in the problem.

The answer is not a specific value for n.

3n < 18

Divide both sides by 3.

3n/3 < 18/3

n < 6

ANSWER: n < 6

What does the answer mean?

It means that n must be less than 6 to make the original inequality a true statement.

Answer:

Step-by-step explanation:

The area of the rectangle is 240 square inches if the length of a rectangle is  8 inches longer than the width. If the ratio of the length to the perimeter is 5:16.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

It is given that:

The length of a rectangle is  8 inches longer than the width. If the ratio of the length to the perimeter is 5:16

As we know, the two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.

Let l and w be the length and width of the rectangle:

l = 8 + w

w = l - 8

l/P = 5/16  (the length to the perimeter is 5:16)

P is the perimeter of the rectangle.

P = 2(l + w)

l/[2(l + w)] = 5/16

16l = 10(l + w)

8l = 5(l + l - 8)

8l = 10l - 40

2l = 40

l =20 inches

w = 20 - 8 = 12 inches

Area = 20x12 = 240 square inches

Thus, the area of the rectangle is 240 square inches if the length of a rectangle is  8 inches longer than the width. If the ratio of the length to the perimeter is 5:16.

Answer: 16.6

Step-by-step explanation:

a² + b² = c²

7² + b² 18²

49 + b² = 324

Subtract 49 from both sides

b² = 275

√b² = √275

b = 16.583

16.583 ≈ 16.6

Answer:

825 g

Step-by-step explanation:

Here's my work:

500g Cl2 l   1mol Cl2  l  2 mol NaCl   l  58.5 g NaCl

                l   71 g Cl2    l  1 mol Cl2      l    1 mol NaCl  

= 823.94  - the rounding can be a little off

The first thing you have to do is convert the 500 g of Cl2 into moles.  So you get the mass of Cl which is 35.5, but Cl is diatomic by itself so you multiply 35.5 x 2 and get 71.   now on the third column you are comparing the mol ratios of the equation.  The equation is 2Na + Cl2 ---> 2NaCl, so you see that there is no coefficient in front of Cl2 so that means there is 1 mol, and then you see that in the product there is a  coefficient of 2 in front of NaCl so that means there is 2 moles.  Then finally you have to convert the moles backs into grams where you just add the masses of Na and Cl .  You multiply across the top  and then divide that number by the bottom row.

Answer:

[tex] a = \dfrac{5}{18} [/tex]

[tex]b = -\dfrac{1}{18}[/tex]

Step-by-step explanation:

You need to rationalize the fraction.

[tex] \dfrac{1}{5 + \sqrt{7}} = a + b\sqrt{7} [/tex]

[tex] \dfrac{1}{5 + \sqrt{7}} \times \dfrac{5 - \sqrt{7}}{5 - \sqrt{7}} = a + b\sqrt{7} [/tex]

[tex] \dfrac{5 - \sqrt{7}}{25 - 7} = a + b\sqrt{7} [/tex]

[tex] \dfrac{5 - \sqrt{7}}{18} = a + b\sqrt{7} [/tex]

[tex] \dfrac{5}{18} - \dfrac{1}{18}\sqrt{7} = a + b\sqrt{7} [/tex]

[tex] a = \dfrac{5}{18} [/tex]

[tex]b = -\dfrac{1}{18}[/tex]

Answer:

x = 17.5

Step-by-step explanation:

[tex] \frac{16}{10} = \frac{28}{x} [/tex] (angle bisector theorem)

Cross multiply

16 × x = 28 × 10

16x = 280

Divide both sides by 16

x = 280/16

x = 17.5

Answer:

C. x^2 + 2x - 1 = 3

Step-by-step explanation:

The standard form of a quadratic equation is

ax^2 + bx + c = 0

We need to use the quadratic formula and the given expression to find the values of a, b, and c.

The quadratic formula is

[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]

Where the formula has -b, the problem has -2, so b = 2.

Now we have

ax^2 + 2x + c = 0

In the denominator, where the formula has 2a, the problem has 2(1), so a = 1.

Now we have

x^2 + 2x + c = 0

Inside the root, the quadratic formula has -4ac. the problem shows -4(1)(-4). Since we already know that a = 1, then c = -4.

Now we have

x^2 + 2x - 4 = 0

Let's look at choice A.

x^2 + 1 = 2x - 3

Subtract 2x from both sides. Add 3 to both sides.

x^2 - 2x + 4 = 0   This is not it!

Let's look at choice B.

x^2 - 2x - 1 = 3

Subtract 3 from both sides.

x^2 - 2x - 4 = 0     This is not it!

Let's look at choice C.

x^2 + 2x - 1 = 3

Subtract 3 from both sides.

x^2 + 2x - 4 = 0     This is it!

Answer: C. x^2 + 2x - 1 = 3

[tex]x^{2} +2x -1=3[/tex] equation could be solved using this application of quadratic formula.

Option D is correct.

A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is  [tex]ax^{2} +bx +c =0[/tex], where a and b are the coefficients, x is the variable, and c is the constant term.

The quadratic formula is used to find the roots of a quadratic equation.

[tex]x=\frac{-b \pm \sqrt{b^{2} -4ac} }{2a}[/tex]

According to the question

[tex]x=\frac{-2 \pm \sqrt{2^{2} -4(1)(-4)} }{2.1}[/tex]

We all know the quadratic formula for finding the factors of a quadratic equation

[tex]x=\frac{-b \pm \sqrt{b^{2} -4ac} }{2a}[/tex]

By comparing two formulas we get a = 1, b = 2, c = -4

Standard form of quadratic equation is [tex]ax^{2} +bx +c =0[/tex]

Substitute a = 1, b = 2, c = -4 in the standard form of quadratic equation

⇒ [tex]x^{2} +2x-4=0[/tex]

We can write it as

⇒ [tex]x^{2} +2x -1=3[/tex]

[tex]x^{2} +2x -1=3[/tex] equation could be solved using this application of quadratic formula.

Option D is correct.
