Question

Evaluate the expression when $p=12 \text{and} q=15$.

6. $q+2$

Short answer

The value of the expression q + 2is 17

Step-by-step solution

Step 1: What is an algebraic expression?

In mathematics, a variable (usually an English alphabet) standing for an unknown value in any equation or Algebraic Expression. In general we used x, y, z or t (time) , d (distance) and r for radius.

Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division).

For example, 7(6y + 9z) is an algebraic expression.

Example of the variable, constant term and the coefficient 

Step 3: Evaluate the expression q + 2 when q = 15 

Consider, the expression provided in the question: $\text{q} \text{+} \text{2}$

To find the value of (q + 2) when q = 15, it is needed to substitute15 for q

The expression will be obtained as: $\text{q} \text{+} \text{2} \text{=15} \text{+} \text{2} \text{=} \text{17}$ [Addition]

The value of the expression q + 2is 17
