Answer:

Step-by-step explanation:
The standard form of an equation of a circle:

(h, k) - center
r - radius
We have the center (-5, 0) and the radius r = 8. Substitute:

3.6m − 2.7 = −1.8m
Subtract 3.6m from both sides:
-2.7 = -5.4m
Divide both sides by -5.4:
m = -2.7 / -5.4
m = 0.5
Answer:
it is correct because it adds up to 180
√144 √ ( 12×12 )=√ (12)² = 12 ⇒ √144 = (12)²
