Can anyone me the answer to the question: "how many times does a typical person eat each week? " is measured in the a. thousands b. tens c. ones d. hundreds

Hi.

Let's assume that the average person has 3 meals a day. No snacks :(

3 · 7 = 21

This is in the tens.

The answer is B.

If you multiply the two numbers, you will have 36 + 78i.
*I assumed you had a typo in the first expression, it is generally written as 6 + 3i. If you meant, 6i + 3i, it should have been just 9i.

To find this product, we use the foil method.

(6 + 3i)(10 + 8i)
60 + 48i + 30i + 24i^2
60 + 78i + 24(-1)
34 + 78i
