Answer:
3
Step-by-step explanation:
Intercept theorem
DE // CB ⇒ 
⇒ 
⇒ ? = 3
1/6(36 + 1/2) = 6 + 1/12 = 72/12 + 1/12 = 73/12
Instead of using PEMDAS or the Order of Operations, the student went ahead and solved the equation as though it were written 6 * 12 - 8.
The correct way to solve would be to first solve the parentheses. 12 - 8 is equal to 4. 4 times 6 is 24, giving us an answer of 24.
