Question

Help please ……………….zzzz

Answer 1

1) I think 15 choose (d)

2) The choose (C) -4fg+4g

3) The choose (d) 3xy/2

4) The choose (a) ab/6

5) The choose (C) 2p+4q-6

6)

`\pi {r}^(2) h = 3.14 * {3}^(2) * 1.5 = 42.39 {m}^(3) = 42.390 {m}^(3)`

Point 6 I think there is an error because the unit m must be m³ because it is r² (m²) and h(m) becomes m³.

I hope I helped you^_^
