Answer:
Yes, it does represent a proportional relationship.
You can see that for every given value of x, the corresponding value of y is twice as much. That means that the first answer is correct; the values are proportional, and the ratio is 2.
Answer:
2 and 3.
Step-by-step explanation:

So if the 3 is on the outside of the parenthesis 3( it means you have to multiply 3 times the numbers inside the parenthesis. 3 X n+7 + 3n + 21. hope this hint helps.
We know that the sandbox is square, and that the area is 160 sq ft. Since A = s^2 for a square, let's work backwards and find s if A = 160 sq ft = s^2.
s^2 = 160 = 16(10). We do this because 16 is the largest perfect square factor of 160.
Then the length of one side of the square is approx. s = 4√10 ft (12.65 ft)
