It whould be 8 because if you divide it
-7, because you distribute it to both -4 and 3.2, which means you're multiplying it to both.
10 sides 180(10-2) 1800-360=1440/10 = 144
Answer:
D
Step-by-step explanation:
28×14=392, which generally already gives you the answer. But the extra area is a trapezoid so we do 4+6=10×2(height)=20, but we have to divide by two since its a trapezoid giving us 10. So 10+392=402
