Answer:
Step-by-step explanation:
a² - b² = (a +b)(a - b)
9x² - 4 = (3x)² - 2²
= (3x + 2 )(3x - 2)
Just plug in 2 for p. 3*2 - 2 = 6-2 = 4
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
Percent decrease=decrease/original times 100
decrease=23.5-21.2=2.3
original=23.5
percent decrease=2.3/23.5 times 100=0.0978 times 100=9.8%
B is answer
