13.45 will be the answer
since we are finding the hypotenuse, the formula is a^2 + b^2 = c^2
this will then be 10^2 + 9^2 = c^2
181=c^2
c=13.45 :)
3(x-8)=12
I got this equation since there are three of the "x-8" sections that add up to the twelve length bar above
Answer i think would be
l-4x+4l
---------
x-1
Answer:
Yes. 3x²y and -5x²y are like terms because the variables x and y have the same exponents.
Answer: 
-3 times the square root of 5
=============================================
Explanation:
Let 
Replace all the root 5 terms with x and we go from

to

From here, combine like terms to get

and the last thing to do is replace the x with sqrt(5)

Meaning that,
