The first five multiples of 9 are
9, 18, 27, 36, 45
The perimeter is 36 yd.
We set up a proportion to represent this situation. We know that the ratio of the side to the perimeter is the same for every square. This means that the ratio of the first square, 2/8 is the same for the second one. We know that the side length is 9, which gives us:
2/8 = 9/x
Cross multiply:
2*x = 8*9
2x = 72
Divide both sides by 2:
2x/2 = 72/2
x = 36
First question, the answer is C. 2nd question, the answer is A
Explanation: I don’t know how to well explain graphs.. however, on the vertical line, that’s the amount of money the person pays after the amount of months they’ve started their plan. Whether that be beginner, or veteran. If you look, the lines overlap a month which is month 4. This is where they both pay 100$, this is because the 100 lines up at that point. For the 2nd question, the beginner would have paid lower than the veteran because the line is below the first. Hope this helps!
