2x^3y+18xy-10x^2y-90y
= 2xy(x^2 + 9)- 10y(x^2 + 9)
= (x^2 + 9)(2xy - 10y)
= (x^2 + 9) 2y(x - 5)
= 2y (x^2 + 9) (x - 5)
Answer:
25
Step-by-step explanation:
5 to the power of 5 is 3125.
because you do 5x5x5x5
then you do 5x5x5 which is 125
3125/125 = 25
Answer:
y= -2/3x+490
slope: -2/3
y-intercept: 490
Step-by-step explanation:
Y-intercept form is y=mx+b, so you would first subtract 2x from both sides to get 3y= -2x+1,470. Then you divide both sides by 3, to get y= -2/3x+490. -2/3 is in the place of m, so it is the slope, and 490 is in the place of b, so it is the y-int.
Answer:
x=2
Step-by-step explanation:
Perimeter of a square = 4*(side of the square)
28 = 4*(3x+1)
28 = 12x + 4
28- 4 = 12x
24 = 12x
x =2
The common number is 6.
72/6=12
60/6=10
12/10
simplify that, it is 6/5
