24
(a) Factorise \(3e^2 + 5e\) (1)
(b) Solve \(7(k - 3) = 3k - 5\) (3)
(c) Make \(a\) the subject of the formula \(f = \dfrac{a + 1}{2}\) (2)
| Answer | Mark | Notes |
|---|---|---|
| \(e(3e + 5)\) | 1 | B1 for \(e(3e + 5)\) |
| Answer | Mark | Notes |
|---|---|---|
| 4 | 3 | M1 for intention to expand brackets eg \(7k - 21\) or division of all terms on RHS by 7 as a first step M1 for correct method to isolate terms in \(k\) in an equation A1 cao |
| Answer | Mark | Notes |
|---|---|---|
| \(a = 2f - 1\) | 2 | M1 for a correct first step eg intention to multiply both sides by 2 A1 cao |
