Form 2 Chapter 3

Algebraic formula is an equation that correlates two or more variables.

• False

• True

Identify whether or not the variable in the brackets is the subject of the formulae

m² = 3+4l [m]

• No

• Yes

Express the variable in brackets as the subject of the formula.

m = 4p-k [p]

• k = (p + k) ÷4

• p = m + k ÷ 4

• p = (m + k) ÷ 4

• No correct answer
