Answer:
5,-5 or C
Step-by-step explanation:
5a² - 44 = 81
Add 44 to both sides of the equation.
5a² = 81 + 44
Simplify.
5a² = 125
Divide both sides by 5, so that we get a² isolated.
a² = 125/5
Simplify.
a² = 25
a = √25
So, a = 5 AND a = -5
It could be both because remember, 5 × 5 = 25, and -5 × -5 = 25, therefore making the statement true.
