Answer:

x=7

Step-by-step explanation:

To set up for this answer, we need to set it up as an equation: 2x+12=5x-9.

get the xs on one side and the whole numbers on the other.

that leaves you with 21=3x.

divide by 3 on both sides to get the answer of x=7

Answer for the first one - it's complicated, but that maths is correct

I kind of cheated and did it a different way than they'd expect. By doing 24 squared, that gives you 576. 

since both angles are 45 degrees, then the sides are equal lengths. Therefore x squared times 2 = 576.

Because of this, x squared = 576 divided by 2, which equals 288.
Therefore the square root of 288 = 12 square root 2
