Answer:
Step-by-step explanation:
<u>Perimeter formula is:</u>
<u>Given:</u>
- l = 2x - 2 and w = x
- P = 86 m
<u>Substitute and solve for x:</u>
- 2(2x - 2 + x) = 86
- 3x - 2 = 43
- 3x = 45
- x = 15
<u>Then find the values of l and w:</u>
- l = 2*15 - 2 = 28 m
- w = 15 m

Simplify. Combine like terms
17k - 10k + 15
(17k - 10k) + 15
17k - 10k = 7k
7k + 15 is your answer
