What is the solution(s) to the equation 5a2 - 44 = 81?
taurus [48]

Answer:

B

Step-by-step explanation:

5a^2 - 44 = 81                     Add 44 to both sides

5a^2 = 81 + 44                    Collect like terms

5a^2 = 125                          Divide both sides by 5

a^2 = 125/5                  

a^2 = 25                              Take the square root of both sides

√a^2 = √25

a = +5

a = -5

The answer is B
