A trapezoid doesn't have any square corners
<span>(4x³-4+7x)-(2x³-x-8) = </span>4x³-4+7x<span> - </span>2x³ + x+8 = (4x³-2x³) + (7x+x) -4+8 =
= 2x³ + 8x +4
(4x³-4+7x)-(2x³-x-8) = 2x³ + 8x +4
Y=30x+18
well if he didn't deliver to any houses he would be paid 18$.
25(6) + [8(6-s)] = t, where s = number of hours and t = total.
