4
(a) Simplify.
(i) \(5x - 6y - x + 3y\) [2]
(ii) \(w^8 \div w^2\) [1]
(iii) \(5c^2d \times 3c\) [1]
(b) Work out the value of
(i) \(4x - 7\) when \(x = 5\), [1]
(ii) \(\dfrac{p + 7}{3}\) when \(p = 2\). [1]
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| (i) \(4x - 3y\) final answer | 2 | B1 for \(4x\) or \(-3y\) in final answer | \(4x + -3y\) scores B1 only |
| (ii) \(w^6\) final answer | 1 | ||
| (iii) \(15c^3d\) final answer | 1 | Accept \(15dc^3\) Do not accept eg \(15 \times c^3 \times d\) | |
