Answer:

shorter side = 7 in

longer side = 12 in

Step-by-step explanation:

Let w = width

then w + 5 = length

The perimeter of the rectangle = 2 widths + 2 lengths.

So, w + w + w + 5 + w + 5 = 38  or 2w +2(w + 5) = 38 are two ways to write the equation to solve the problem.

Now 4w + 10 = 38

4w = 28

w = 7

w + 5 = 7 + 5 = 12

shorter side = 7 in

longer side = 12 in

Check:  7 + 7 + 12 + 12 = 38 = perimeter

9(6-2v)= -12(v-8)<br> step-by-step explanation please!<br> Enter only the value of the variable
WINSTONCH [101]

Answer:

v = -2.5

Step-by-step explanation:

9(9-2v) = -12(v-8)

81−18v= −12v+96

So move -18v to the other side and change the sign. Same to 96.

81-96 = -12v + 18v

-15 = 6v

v = -2.5
