A 4B zC 13D 9

The coefficient is the number multiplying the variable.

A \(3n + 5\)B \(3 + n + 5\)C \(3(n + 5)\)D \(3n \times 5\)

The sum n + 5 must be grouped before multiplying by 3.

A 3B 2C 1D 5

The terms are 5a, 3b, and 7, which are added.

A \(9 + t\)B \(\frac{9}{t}\)C \(t – 9\)D \(9t\)

Cost = price per ticket times number of tickets.

A the product of \(x\) and 4B the quotient of \(x\) and 4C 4 divided by \(x\)D 4 less than \(x\)

x/4 is x divided by 4.

A \(3s\)B \(s + 3\)C \(s – 3\)D \(\frac{s}{3}\)

3 more than s is s + 3.

A twice the difference of \(n\) and 6B the difference of twice \(n\) and 6C 6 less than twice \(n\)D the sum of \(n\) and 12

The difference n – 6 is multiplied by 2.

A \(4k + 5\)B \(4(k + 5)\)C \(5k + 4\)D \(9k\)

4 times k is 4k, and 5 more is + 5.

A 8B 11C 2D 21
