Answer:
10
Step-by-step explanation:
The expression ab + c means that we have to sum two terms.
The first term is ab, which is the product of a and b (the multiplication sign is often dropped when obvious). Since a = 2 and b = 3, their product is 2x3 = 6.
The second term is simply c, which we know is equal to 4.
So, we have a sum, and the two terms are 6 and 4. The sum is 6+4 and the result is thus 10.
