The perimeter is 72 and P=2(L+W), furthermore, L=2W so altogether...

2(L+W)=72  and using L=2W in this we have:

2(2W+W)=72

3W=36

W=12 and since L=2W

L=24

So the length is 24cm and the width is 12cm.

Choose Yes or No to tell whether the expressions are equivalent. 1. 4(5c + 3) and 9c + 7 yes or no 2. 10f – 10 and 2(8f – 5) yes
Juli2301 [7.4K]

Answer:

1) No

2) No

3)Yes

4)No

Step-by-step explanation:

Distributive property: a(b + c) =a*b + a*c

1) 4(5c + 3) = (4*5c) + 4*3

                  = 20c + 12

NO

2) 2(8f - 5) = (2*8f) - (2*5)

                 = 16f - 10

NO

3) 3(4g + 7) = (3*4g) + (3*7)

                  = 12g + 21

YES

4) 6(4j - 6) =(6 * 4j) - (6*6)

                = 24j - 36

NO

Rudik [331]

Among the students who did not make the honor roll. Then the relative frequency of having no curfew will be 7.

<h3>How to find the relative frequency?</h3>

Relative frequency is the ratio of the considered sub-group count to the total count. (so its frequency of the considered sub-group relative to the total frequency).

                                     Curfew                 No Curfew No

Honor Roll:                       18                                10

No Honor Roll:                 2                                  7

Among the students who did not make the honor roll.

Then the relative frequency of having no curfew will be 7.
