If a= .75 and b= .50, what is the perimeter of the rectangle?
Lerok [7]

Answer:

  C.  14 inches

Step-by-step explanation:

  P = 2((4a +3) +(6b -2) = 8a +12b +2

For the given values, this is ...

  P = 8(0.75) +12(0.50) +2 = 6 + 6 + 2 = 14

We just need to solve the equation in order to find the value.

3f+5=32

So we subtract 5 from both sides of the euqation and get

3f=27

Now we divide by 3 on both sides and get

f=9

So the answer is C.
