When solving the equation, which is the best first step to begin to simplify the equation? -2(x+3)=-10
O (-2)(-2)(x+3) =-10(-2)
0-3(-2)(x+3) --10-2)
{(x+3)-510
o Zo(x+3) = -10

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
