Answer:
2
Step-by-step explanation:
5y-2x
5(2)-2(4)
10-8=2
For the square root of a negative number, you would have to get into imaginary numbers. If you haven't learned about it yet, then the answer would be no real solutions. But if you have, here's how to solve it:
First, identify that 9 x 3 = 27. To after taking the square root, you will get 3√3 (Since the square root of 9 is 3 and there's no square root of 3, so leave it in the √)
However, since it is a negative number, you will have to include the letter i in the answer. i represents the imaginary part of it since you can't have a negative number in the square root.
So your answer will look like 3i√3.

Answer:
45
Step-by-step explanation:
(27*27)+(36*36) = 2025
square root 2025 and you get 45
to check 45*45=2025
Answer:
31
Step-by-step explanation:
Because these two angles are supplementary, their angle measures must add up to 180 degrees. Therefore:
3x+2+2x+23=180
5x+25=180
5x=155
x=31
Hope this helps!
