Answer:
No
Step-by-step explanation:
For x and y to have a proportional relationship, then
the ratio of k = 
must be equal for all points
(2, 5) → k = 
= 2.5
(3, 7.5) → k = 
= 2.5
(5, 12.5) → k = 
= 2.5
(18, 8) → k = 
= 2.25 ≠ 2.5
k is not equal for all values , hence no proportional relationship exists

Answer:
the factored equation is ((x^3) + 3x^2) + 2x = 0
Step-by-step explanation:
*The ^ means to the power of.
so you should start off by splitting it into ways, like isolate 2x and start with x^3 and 3x^2, if thats the wrong answer u are not looking for then the other formula is x^3 + 3x^2 + 2x = x • (x^2 + 3x + 2), again just splitting it into ways. since we know the equation is = to 0, we put 2 of them together, and since you can divide everything by x and just put x outside to keep it the same, it would become x^3 + 3x^2 + 2x = x • (x^2 + 3x + 2).
