Answer:
I cant see the image that good
Step-by-step explanation:
24.5, 2 sides are 7 and 7x7=49. then you have to divide by two because it is a triangle so the answer is 24.5
A = b - 2
a - 3b = 22
(b - 2) - 3b = 22
b - 2 - 3b = 22
-2 - 2b = 22
-2b = 24
-b = 12
b = -12
a = b - 2
a = -12 - 2
a = -14
Solution set {-14, -12}
