A = C. Msg if u need more help :3
B. It’s because If you use the pythagorean theorem it is A squared + B squared = C squared.
4 squared= 16
+
15 squared= 225

241 squared
the square root of 241 is about 15. There could be more but that’s all that come to mind for me rn
"What percent" is our unknown x, "of" means we will multiply, "is" means equals. We set up the equation accordingly: x(12.5) = 39. 12.5x = 39. Divide both sides by 12.5 to get x = 3.12. To get to the percent form we multiply by 100 to get 312%.
Answer:
Step-by-step explanation:
x^3+3x^2-x+2x^2+6x-2
To simplify this expression completely we combine like terms
3x^2 and 2x^2 are like terms
3x^2 + 2x^2 is 5x^2
-x and 6x are like terms
-1x + 6x is 5x
We cannot simplify more because all terms are unlike terms.
