For Part A, my answer was 435 since I multiplied 5 x 87 = 435. For Part B, my answer was 540 since I multiplied 22.5 x 24 = 540.

Both of my answers were incorrect. How should I approach this problem?

a. 36.25 ft

b. 45 ft

Step-by-step explanation:

GIVE YOUR ANSWER IN FEET !!! as the problem statement says.

not in inches. when you use the scale factor with inches, you get inches as result. then you need to convert them to feet.

how many inches in 1 ft ?

12 !

so, you need to divide your results by 12 to get the feet.

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
