They arent equivalent because the simplified version of 3(5x) is 15x and the simplified version of the other one is 45x.

Hope this helps!!

Well, let’s start with simplifying both of them. 3(5x) simplifies down to 15x. For (3*5)(3*x), you have to use FOIL. Using FOIL you get 9+3x+15+5x, which by combining like terms you get 8x+24. These are clearly not equal (equivalent). You can explain that solving them produces different results and give the process I used to solve both of them.

The answer is x=7. Since the two angles are corresponding. Then it would be 10x-2=9x+5. The answer would be x=7. Please mark me Brainleist

Radius of a sphere that has a surface area 12.56in2 use 3.14

enot [183]

$\bf \textit{surface area of a sphere}\\\\
A=4\pi r^2\qquad 
\begin{cases}
r=radius\\
-----\\
A=12.56
\end{cases}\implies 12.56=4\pi r^2
\\\\\\
\cfrac{12.56}{4\pi }=r^2\implies \sqrt{\cfrac{12.56}{4\pi }}=r$
