Question

c. 7 copies of the sum of 8 and 4, less 2

Explanation:

Step1: Find the sum of 8 and 4

First, we calculate the sum of 8 and 4. The sum of 8 and 4 is $8 + 4 = 12$.

Step2: Find 7 copies of this sum

Next, we find 7 copies of the sum we just calculated. That means we multiply the sum (12) by 7. So, $7\times12 = 84$.

Step3: Subtract 2 from the result

Finally, we subtract 2 from the result we got in Step 2. So, $84 - 2 = 82$.

Answer:

82
