Volume = Length x Length x Length
Volume :
(x + 2) (x + 2) (x + 2)
= (x² + 4x + 4)(x + 2)
= x³ + 2x² + 4x² + 8x + 4x + 8
= x³ + 6x² + 12x + 8
Answer: x³ + 6x² + 12x + 8
Answer:
16
Step-by-step explanation:
area of big triangle is 36
area of small triangle is 20
area of shaded is 36 - 20=16
D 22-14=8 14-7=7 7 of 14=50% so i think that’s the best estimate
16.454 is greater than 16.45.
