Answer:
16x⁴+16x³-12x²-32x-16
Step-by-step explanation:
(8x²-4x-8)(2x²+3x+2)
= 16x⁴+24x³+16x²-8x³-12x²-8x-16x²-24x-16
= 16x⁴+16x³-12x²-32x-16
Answer:
w = 4 m
Step-by-step explanation:
The volume (V) of a cuboid is
V = lwh ( l is length, w is width and h is height )
Given V = 144 m³, then
lwh = 144 ( substitute l = 3 and h = 12 )
3 × w × 12 = 144
36w = 144 ( divide both sides by 36 )
w = 4
