Answer:
8, 10
Step-by-step explanation:
Multiplying the equation by the product of the denominators, we have ...
40(x+2) +40x = 9x(x+2)
80x +80 = 9x^2 +18x . . . . eliminate parentheses
9x^2 -62x -80 = 0 . . . . . . put in standard form
9x^2 -72x +10x -80 = 0 . . . prepare to factor by grouping
9x(x -8) +10(x -8) = 0 . . . . . factor pairs of terms
(9x +10)(x -8) = 0
Solutions are ...
x = -10/9 and x = 8
The integers are 8 and 10.

I find a graphing calculator to be a nice tool for solving these. It finds zeros easily, so writing the equation so it equals zero is a useful first step.
Answer:
31.42
Step-by-step explanation:
radius= half diameter
circumfrence= 2pi*r
2291731.59722
I dont really know how to get it, i just put 55/72x3000085 in the calculator and it said that
791 since it has no decimal places
Answer: well, just multiply x and y by the scale factor
Step-by-step explanation:A square with a perimeter of 20 units is graphed on a coordinate grid. The square is dilated by a scale factor
of 0.4 with the origin as the center of dilation.
If (x, y) represents the location of any point on the original square, which ordered pair represents the
coordinates of the corresponding point on the resulting square.
