Expand the brackets by multiplying everything in the brackets by -0.25.
-x x -0.25 = 0.25x
-12 x -0.25 = 3
0.25x + 3 = 2
-3 from both sides.
0.25x = -1
Divide both by 0.25
x = -4

Answer:
20. 300π m³
21. 457 1/3 π cm³
Step-by-step explanation:
20. r = 10 ÷ 2 = 5
V = 5² × 12 × π = 25 × 12π=300π m³
21. r = 14 ÷ 2 = 7

V = 457 1/3 π cm³
