Question

What is the solution of sqrt x+2 - 15 =-3

Answer 1

Answer:

A)  x=142

Step-by-step explanation:

I just got a 100 on the quiz from edge.

Answer 2

I hope the given equation is :

$\sqrt{x+2} -15 =-3$

First step to solve the above equation is to add 15 to each sides of the equation. Therefore,

$\sqrt{x+2} -15+15 =-3+15$

$\sqrt{x+2} =12$

Next step is to remove square root from the left side, so let's square on each sides of the equation. So,

x + 2= 12²

x + 2 = 144

x = 144 - 2

So, x = 142

So, a is the correct choice.

Hope this helps you!
