Answer:
330 square inches
Step-by-step explanation:
99 x 5 =495
495 x 2/3 =330
D. -4
the slope formula is
m=(y2-y1)/(x2-x1)
(x2,y2) = (4,7)
(x1, y1) = (5,3)
So (7-3)/(4-5) = 4/-1 = -4
Assuming 5a3 equals 5a^3, and the same for everything else, you would plug in 4 for a, so 5(4)^3 - 2(4)^2 + 4 - 45, which equals 247.
x= -5/2
4 - (2x+4)=5
4-2x-4=5
-2x=5
x=-5/2
