Answer:
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
