Question

a) evaluate 5(3 + x) when x = 0.
5(3 + x) = 5(3 + 0)
= 15
b) evaluate 5(3 + x) when x = 1.
5(3 + x) = 5(3 + 1)
= \square

Explanation:

Step1: Calculate inside the parentheses

First, we solve the expression inside the parentheses: \(3 + 1 = 4\). So now our expression becomes \(5\times4\).

Step2: Multiply the results

Now we multiply 5 by 4. \(5\times4 = 20\).

Answer:

20
