Please help

Answer 1

Hello,

To solve this equation, you first take the square root of both sides.
This will give you two options, because the square root of 64 could be 8 or -8.

Your equations are:
x + 3 = 8  or  x + 3 = -8

Solving these equations give the solutions: x = 5 or x = -11
Option A is correct.

You can verify that it is correct by inputting the solutions and evaluating the expression.

I hope this helps, good luck!
