Step-by-step explanation:
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.

Red Box:
Top: 12.57 Top: 78.54
Bottom: 12.57 Bottom: 78.54
Rectangle: 32 Rectangle: 110
SA: 125.66 SA: 502.65
Yellow Box:
#1: 1156.1
#2: 88
Green Box:
#1, Top Left: 3103.9
#2, Bottom Left: 716.3
#3, Top Right: 495.4
#4, Bottom Right: 325.7
Blue Box:
#1: h=8
SA=2πrh+2πr²
527.8=2(3.14)6h+2(3.14)(6)²
527.8=6.28(6)h+(6.28)(6²)
527.8=37.68h+(6.28)(36)
527.8=37.68h+226.08
-226.08 -226.08
301.72=37.68h
301.72/37.68=37.68h/37.68
8=h
#2: h=0.87
