Answer:

x=3

Step-by-step explanation:

so...

13=x²+4.

start by subtracting 4 from each side to get the numbers on one side.

13-4=, and 4-4=0

now, we just have 9=x².

to undo a square, one must square root. so,

\sqrt{9}  = 3

and

\sqrt{x {}^{2} }  = x

now, x=3.

Help this confusing no matter how any times I do it
3241004551 [841]

Answer:

The variable 8. Equation is 16 + 12x = 112.

Step-by-step explanation:

We know that she spent $16 dollars on magazines, so we can put it in the equation (16 + x= ?). We also know that the total is $112, so we can also add that (16+ x= 112). We don't know how many books she got, but we do know how much they cost (16 + 12x=112. So that makes  the books the variable (X).

To find the variable we need to take out the magazines from the price. 112-16=96. Now we're left with 12x=96. Now all we have to do is divide 96 by 12, which equals 8.

Sorry everything is so long, I tried to make it short as possible
