Answer:
Step-by-step explanation:
Let the width be x
- Then the length is 3x + 2
- Perimeter = 66
<u>Perimeter formula</u>
<u>Substitute values</u>
- 66 = 2(3x + 2 + x)
- 33 = 4x + 2
- 4x = 31
- x = 31/4

Answer:
is this homewwork or a test?
Step-by-step explanation:
Answer:
try putting an imaginary 1 in front of your variable (c). so
1c + 4c = 15
combine like terms
(1c + 4c) = 5c
therefore we have
5c = 15
now, divide BOTH sides of the equation by 5
5c/5 = 15/5
5c/5 = c
15/5 = 3
c=3
