What is the value of the following expression when evaluated for q = 3?
4q + q 2
18
21
49
52
21
To find the value of the expression 4q + q^2 when q = 3, we substitute q = 3 into the expression and simplify.
Substituting the value of q = 3 into the expression, we have:
4(3) + (3)^2
Simplifying the expression:
12 + 9
Adding the values:
21
Therefore, the value of the expression 4q + q^2 when q = 3 is 21.
