Answer:
5
Step-by-step explanation:
evaluate f(4) by substituting x = 4 into f(x) and g(2) by substituting x = 2 into g(x)
f(4) = (3 × 4) - 3 = 12 - 3 = 9
g(2) = (2 × 2 ) = 4
f(4) - g(2) = 9 - 4 = 5
Answer:
1.25
Step-by-step explanation:
A cube has six faces so 48/6 is the length of one edge.
Volume of a cube is length times breadth times height
so 48/6= 8
A cube has equal length of sides
So 8x8x8= 512cm^3
