Answer:
=3x³+2x²−27x−18
Step-by-step explanation:
(x+3)(x−3)(3x+2)
=((x+3)(x−3))(3x+2)
=((x+3)(x−3))(3x)+((x+3)(x−3))(2)
=3x³−27x+2x²−18
=3x³+2x²−27x−18
Answer:
1. 27.5 in.^2
2. 360 in.^2
Step-by-step explanation:
1.
A = bh/2
A = (4 + 7)(5)/2
A = 27.5 in.^2
2.
A = bh/2
A = (35 + 13)(15)/2
A = 360 in.^2
40 percent
