Answer:
74 and 740
Step-by-step explanation:
So the first thing you want to do is solve what's in the parentheses (4^2-3) before you subtract, you get rid of the exponent by doing 4 times 4 (also known as 4^2) to get 16. you then subtract 3 from 16 getting 13. you then multiply7 by 13 to get 91, where you add the 8 to get 99 which would be the final answer
The answer is c. To find an average, you add all of the numbers and divide by the amount of numbers you added together. Since you have to add them first, they are in parentheses. You divide by 3 because there are 3 numbers.
