the answer would be 91 customers
ok to start off i'm pretty sure you meant to put (3x^2) rather than 3x^3, but i'll just ignore that part, so we first want to remove the parentheses and we add 6x^2-5x+3+3x^2+7x-8 so, we simplify and get: 9x^2+2x-5.
which is c.
if this mark me brainliest, and hit button!
slope = (y2 - y1)/(x2 - x1)
= (4 + 6)/(-2 + 5)
