If using the method of completing the square to solve the quadratic equation x^2+ 15x – 11 = 0, which number would have to be added to "complete the
square"?

the answer is c 150

step-by-step explanation:

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
