Answer:
20
Step-by-step explanation:
Because it is a square table, that means all the sides are even. And to find the area, we do Height * Base. But again, because they're even, we would just need to find 2 numbers that multiply to be 400. And that number, is 20. 20 * 20 = 400. So the length of one side is 20.
Answer:
y = 16/9
Step-by-step explanation:
Assuming "y" is a variable
3y - 6/9 = 4 - 2/-3
3y - 2/3 =14/3
3y - 16/3 = 0
1/3 (9y - 2) = 14/3
ANSWER = y : 16/9
Yes because no same x-valu resulted in different y-values.
Each term differs by -68 and the first term is -68, we have:

As an expession it's just -68n.
