Answer:

a=5,a=-5

Step-by-step explanation:

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.
