Answer:
x = -8 please mark brainliest
Step-by-step explanation:
Pull out like factors :
-x - 8 = -1 • (x + 8)
Equation at the end of step 1 :
Step 2 :
Solving a Single Variable Equation :
2.1 Solve : -x-8 = 0
Add 8 to both sides of the equation :
-x = 8
Multiply both sides of the equation by (-1) : x = -8
137.1
You would find the area of the semi circle by using the circle formula and dividing by 2, which would be 8
Then find the area of the rectangle, which would be 112.
T is the first one bc it is just look it up
