To find an expression equivalent to the answer, I simply factored the expression
10q+<span>5
</span><span>10q</span>+<span>5 = 5(2q+1)</span>
If this wasn't one of the answer choices please notify me
Use the Pythagorean theorem for this. (a^2+b^2=c^2)
a=9, b=12, c=x
9^2+12^2=c^2
81 + 144 = c^2
225 = c^2
c =15
the answer is c
-8 - 7x is the factored version.
