Answer:
?
Step-by-step explanation:
I can't see anything attached but I know all angles of a triangle add up to 180 degrees. It probably doesn't help tho.
6x = -12
6x/6 = -12/6
x = -2
Answer:
perimeter you add all sides together:
5x+2 +5x+2 +x +8 +x+8
12x +20
and for Area you multiply:
(x + 8)(5x + 2)
5x^2 + 2x + 40x +16
5x^2 +42x +16
so your answer is the first one or "A"
1 because it is reveresed
