Answer:
P = 6x-2
x = 14
Step-by-step explanation:
To find the perimeter, we add the sides
P = 4x-8 + 3-2x + 5x+3
Combine like terms
P = 4x-3x+5x -8+3+3
= 6x -2
Now we know the perimeter
82 = 6x-2
Add 2 to each side
82+2 = 6x-2+2
84 = 6x
Divide each side by 6
84/6 = 6x/6
14=x
Answer:
A) 7x - 2
B) x = 12
Step-by-step explanation:
4x - 8 + 3 - 2x + 5x + 3
7x - 2
7x - 2 = 82
7x = 84
x = 12
