For this case we have the following expression:

For this case what you should do is observe the terms that are repeated in the given expression.
We have then:

It is the term that is present in the whole expression.
Therefore, by doing common factor we have:
Answer:
the GCF is:
option A: a 3 is missing at the beginning of the option.
The answer is 28.2 because 479.4 ft. ÷ 17 ft. = 28.2 ft.
Zero is the opposite of it self because nothing can goes into zero. Zero can never be lower them a negative number order than a positive number.
The answer to your first question would be B, because in the word problem it says that she buys 6 pots, so therefore we can eliminate A and C. We are left with B and D. Now looking at the second equation, we see that x represents the 5 inch pots, which are $12. This would mean 12x, because if she bought 1 5 inch pot, she would spend $12, and the same way, 10 inch pots are represented by y, or $15. Pretty much, multiply the number of 10 inch pots she buys by 15. Therefore the answer is B.
Question 3 says that the sum of their ages are 105. So the first equation should be S + R = 105. The second part of the question says that Sara is 33 years younger than Rolando. This means 33 + Sara's age, represented by S, should equal Rolando's age. That is S + 33 = R.
