Is the following shape a rectangle? How do you know?

Answer:

Louis score would be 2

Step-by-step explanation:

Answer:

2x - 2y

Step-by-step explanation:

P = 7x + 2y

P =a + b + c

7x + 2y = 2x + y +3x - 5y + c

7x + 2y - 5x - 4y

= 2x - 2y

Answer:

6 x 2 = 12

8 x 4 = 32

6 x 2 = 12

4x+10

=2(2x+5)

b. 3x−12+6x+9

=3(3x−1)

Step-by-step explanation:

Answer:

2 x 10^5

200,000 / 10 = 20,000

20,000 / 10 = 2,000

2,000 / 10 = 200

200 / 10 = 20

20 / 10 = 2

I divided 200,000 by 10 five times to get a number less than 10.

So, 5 is going to be the exponent.

Question Explanation:

In other words you can write 200,00 using a whole number and a power 10 using scientific notation!

In scientific notation you want a number less than 10 multiplied by 10 to the power of a number.

Solution:

200,000 / 10 = 20,000

20,000 / 10 = 2,000

2,000 / 10 = 200

200 / 10 = 20

20 / 10 = 2

I divided 200,000 by 10 five times to get a number less than 10.

So, 5 is going to be the exponent.

Answer:

-9x^2 + 12x + 5

Step-by-step explanation:

I'm assuming you meant (3x – 2)^2.  The " ^ " indicates exponentiation and is required.  We then have:

9 - (3x – 2)^2, which, when expanded, is

9 - (9x^2 -12x + 4), or:

-9x^2 + 12x + 5

Step-by-step explanation:

you score is 20, including bonus points. x=scor without bonus. that means that your normal score plus the bonus equals 20. so x +2=20

Option d is correct, ,[tex]ac+ad+ae+bc+bd+be[/tex] is the equivalent expression of [tex](a+b)(c+d+e).[/tex]

The expression [tex](a+b)(c+d+e)[/tex] can be expanded using the distributive property.

We multiply each term in the first set of parentheses by each term in the second set of parentheses and combine like terms.

[tex](a+b)(c+d+e) = a(c+d+e) + b(c+d+e)[/tex]

Expanding further:

[tex](a+b)(c+d+e) = ac + ad + ae + bc + bd + be[/tex]

Hence,[tex]ac+ad+ae+bc+bd+be[/tex] is the equivalent expression of [tex](a+b)(c+d+e).[/tex]

Answer:

option (B) 33 is right answer

Answer:

Step-by-step explanation:

According to Supplementary Angle sum,

104° + x + x + 10° = 180°

=> 2x + 114 = 180

=> 2x = 180 - 114

=> 2x = 66

Answer:

(13/2)^27

Step-by-step explanation:

First note that ( )^0 = 1, so we need not bother with the last term.

Next, note that

 (2/13)^(-6) divided by (2/13)^3 is (2/13)^(-9).

Finally, we must cube this last result.  We get:  (2/13)^(-9*3) = (2/13^(-27)

or

(13/2)^27

Note:  we're "evaluating" an algebraic expression here, not "solving it," since there is no equation here.

Step-by-step explanation:

We are given the an area of

173.6 cm

and a height of 9 cm.

We also know that the formula for area is lw, meaning we can substitute the area for lw

in the volume formula.

Now let's plug in what we know into the formula and solve for the volume:

V=(173.6 cm2)(9 c)=1562.4 cm3 The volume of the rectangular prism is

1562.4 cm3

Answer: 6(x+8)=66

Step-by-step explanation:

Answer:

3.27

Step-by-step explanation:

Let us assume that the values are the side of a right triangle where;

Hypotenuse = 6 (longest)

Angle of elevation = 33 degrees

Required

x = opposite side

Using the trig identity

Sin theta = opp/hyp

Sin 33 = x/6

x = 6sin33

x = 6(0.5446)

x = 3.27

Hence the value of x is 3.27

Note that the values of the sides are assumed.

Step-by-step explanation:

Answer:

both (x - 5) and (x - 3) are factors of x^2  - 2x + 15

Step-by-step explanation:

Please write this all on one line:  x^2  - 2x + 15.

Recognize that 3*5 = 15.  Possible factors of x^2  - 2x + 15 are thus (x - 5) and (x + 3).  Multiplying these together results in x^2  - 2x + 15, so we have verified that both (x - 5) and (x - 3) are factors of x^2  - 2x + 15.

f(x) = x² - 2x + 15

This function f(x) will have the negative "discriminant" in root ; thus forming complex roots

So this function has no rational roots

89 total left handed students

Step-by-step explanation:

Multiply 320 x 0.2

Multiply 250 x 0.1

You can think of it this way, 0.2 is 2/10 and 0.1 is 1/10 so take 20 percent of 320 and 10 percent of 250

Add them up for your answer 64 + 25 = 89
