Answer:
B) x=12
Step-by-step explanation:
x+22+4x+2= 5x+24
5x+24=84
5x=60
x=12
First add 14+2 so you have sqrt(x) +14=x. Next subtract the 14 to the other side and square both sides, so you have x=x^2+28x+196. Now subtract the x, then use quadratic formula to get the two solutions for the way you have the question typed. However, since I recognize this as being a test question from your FLVS course that is not typed correctly with the parenthesis that will give you the wrong answer. A better idea would be to review through the examples in the lesson, try a few practice problems, then you can easily solve by isolating the square root on one side by itself, then squaring both sides.

The first thing you should do is do everything in parenthesis.
So lets start:
(2*4) = 8
(3*55) = 165
(2+7) = 9
Now we add and subtract the numbers:
8 + 165 - 9 = 164
So that means that the answer is 164.
Hope this helps!!! :)
