Answer:
x = 5
Step-by-step explanation:
Given that,
First side of a triangle = x+2
The second side of a triangle = 8
The third side of a triangle = x
We know that, perimeter is equal to the sum of all sides. So,
x+2+x+8 = 20
2x+10 = 20
2x = 10
x = 5
Hence, the value of x is equal to 5.

Answer:
a = -3
Step-by-step explanation:
Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other.
Divide -8 from both sides:
(-8a)/-8 = (24)/-8
a = 24/-8
a = -3
a = -3 is your answer.
