Answer:
Width=8, Length= 20.
Step-by-step explanation:
The equation can be set up as :P=2L+2W
Insert the values : 56=2L+2(8)
Simplify: 2L=56-16=40
Answer :L=20
-2x +7 = 3x - 8
Move the variable to the left-hand side and change its sign
-2x -3x+ 7 = -8
Move the constant to the right-hand side and change its sign
-2x -3x = -8 -7
Collect like terms
-5x = -15
Divide both sides of the equation by -5
x=3
Multiply 6x5= 30, 30 + 4 = 34
Then 7x5= 35, 35 + 4 = 39
34+39 = 73
73/5 = 14.6 or 14 3/5
