Question

Evaluate the expression when a=4, b=15, and c= 16.

4a +3

A) 60
B) 56
C) 57
D) 59

Answer 1

This would be impossible to answer. The reason is because none of the answer match the actual answer of the problem, did you write the equation wrong or is that all the options for the answer?

It would be 4(4)+3 because a=4 meaning 4•4=16 + 3 = 19

Answer 2

Given that;

a = 4

We plug this value into our equation, and solve.

So:-

4a + 3

4(4) + 3

16 + 3

= 19
