Answer:
Here
Step-by-step explanation:
length = x
width = 2x - 3
Perimeter = 2length + 2 width
2x + 2(2x - 3) = 42
2x + 4x - 6 =42
6x - 6 = 42
Add 6 to both sides
6x = 48
Divide both sides by 6
x = 8
Length = 8 inches
Width = 2(8) - 3 = 16-3 = 13 inches
A is 24, B is 17, C is 25, D is

Hey!
--------------------------------
Solution:
3x - 6 = -4
3x + (-6) = -4
3x + (-6) + 6 = -4 + 6 (Add 6 to both sides)
3x = 2 (Simplify)
3x/3 = 2/3 (Divide both sides by 3)
x = 2/3 (Simplify)
--------------------------------
Answer:
x = 2/3

Hope This Helped! Good Luck!
