Answer
which of the binomials below is a factor of this expression?
9x^2 + 48xy +64y^2
a. 3x - 8y
b. 3x + 8y
c. 3x + 16y
d. 3x - 16y

If you simplify the ratio to 2: 1, this shows that for every two people who liked lemonade, there was one that liked iced tea. so, divide 39 by 3. that equals 13, so 13 + 13 = 26 and you would add 13, which is 39. so, 26 people liked lemonade, and 13 liked iced tea.
