Evaluate the expression when a = 6, b = 3 and c = 2:
c(b + a ) – a =

12

Step-by-step explanation:

We have the expression:

c(b+a)-a

We know that a is equal to 6, b is equal to 3, and c is equal to 2. Therefore, we can substitute 6 in for a, 3 in for b, and 2 in for c.

2(3+6)-6

Now, solve according to PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

First, solve inside of the parentheses. Add 3 and 6.

2(9)-6

Next, multiply 2 and 9.

18-6

Subtract 6 from 18

12

So the right answer is 12.
