Answer:
y x (2x +y) x (7x +y)
Step-by-step explanation:
14x^2y + 9xy^2 +y^3
(Factor the expression)
y x (14x^2 +9xy +y^2)
(Rewrite the expression)
y x (14x^2 + 7xy +2xy +y^2)
(Factor the expression)
y x (7x x(2x +y) + y x (2x +y) )
(Factor the expression)
y x (2x +y) x (7x +y)

Step-by-step explanation:
The sum of all of the interior angles can be found using the formula S = (n - 2)*180. It is also possible to calculate the measure of each angle if the polygon is regular by dividing the sum by the number of sides.
Answer:
Solution: (-4, 2), x= -4 and y =2
Step-by-step explanation:
-8x - y = 30
-2y = x
Substitute for x
-8*(-2y) - y = 30
16y - y = 30
15y = 30
y = 30/15 = 2
Then x = -2y = -2*(2) = -4
Solution: (-4, 2), x= -4 and y =2
