(a) Expand \(3(4 - 2x)\) (1)
(b) Solve \(\dfrac{3y}{4} = 12\) (2)
(c) Factorise \(4p + 6\) (1)
| Answer | Mark | Mark scheme |
|---|---|---|
| \(12 - 6x\) | B1 | for \(12 - 6x\) (accept \(-6x + 12\)) |
| Answer | Mark | Mark scheme |
|---|---|---|
| 16 | M1 | for a correct first step, eg \(3y = 12 \times 4\ (= 48)\) or \(\dfrac{y}{4} = \dfrac{12}{3}\) |
| A1 | cao |
Additional guidance
Do not accept ambiguous algebraic expressions
| Answer | Mark | Mark scheme |
|---|---|---|
| \(2(2p + 3)\) | B1 | cao |
Additional guidance
Do not accept equivalent expressions not fully factorised
