The question, in short

Rearrange P = Ty to make T the subject, then expand and simplify the product (x + 8)(x − 5).

Summarised in our own words. Use the official paper for the exact wording and any diagrams.

Part (a) · 1 mark

Rearrange the formula P = Ty so that T is the subject.

  1. 1Divide both sides by y
  2. 2T = P/y

AnswerT = P/y

Part (b) · 2 marks

Expand the brackets in (x + 8)(x − 5) and simplify the result.

  1. 1(x + 8)(x − 5) = x² − 5x + 8x − 40
  2. 2= x² + 3x − 40

Answerx² + 3x − 40
