A) draw a cube
i) 16cm
ii) 80 cm
b)64 cm
Ok so draw the outline of a cube with 4cm each. There is six sides and the area is just multiplying 4 by 4. So, since the area of each side is 16, and there is 6 sides, the surface area is 80 cm. The volume is just length x width x height (4x4x4) so it’s 64 cm cubed.

y = 1
Answer: 1 or D
Answer:
h(-2) = 13
h(0) = 9
h(5) = -1
Step-by-step explanation:
when h(-2)
h(-2) = -2*-2 + 9
h(-2) = 4 + 9
h(-2) = 13
when h(0)
h(0) = -2*0 + 9
h(0) = 9
when h(5)
h(5) = -2*5 + 9
h(5) = -10 + 9
h(5) = -1
