Question

If (a = 12) and (b = 2), solve ab + (3a - 8b).

A. 80
B. 84
C. 88
D. 92

Answer 1

After substituting a = 12 and b = 2 into the expression ab + (3a - 8b), it simplifies to 44, which is the final answer after performing the arithmetic operations.

Step-by-step explanation:

To solve the expression ab + (3a - 8b) given that a = 12 and b = 2, you need to substitute the values of a and b into the expression and then perform the arithmetic operations.

Steps to Solve:

1. Substitute a = 12 and b = 2 into the expression.
2. Multiply a and b to find ab.
3. Treble the value of a to get 3a.
4. Octuple the value of b to get 8b.
5. Add ab to 3a and subtract 8b to get the final result.

Let's calculate:

• ab = 12 * 2 = 24
• 3a = 3 * 12 = 36
• 8b = 8 * 2 = 16
• So, 24 + (36 - 16) = 24 + 20 = 44

Therefore, the solution is 44.
