F(x) = 3x + 9
g(x) = 5x²

(f + g)(x) = (3x + 9) + 5x²
(f + g)(x) = 3x + 9 + 5x²
(f + g)(x) = 5x² + 3x + 9

jonathan has a collection of 400 marbles. Blue marbles make up17%, percent of his collection. How many blue marbles does Jonatha
dsp73
17% of 400 is 68.
Another way u can do it is 17% of 100 four times since its easier to do. 
17% of 100 is 17.
we have to do this 4 times since 100 goes into 400 four times.
So 17*4 =68

Monique drew a square and inscribed circle on a sheet of paper, as shown below
Irina-Kira [14]
If you know the area of the square is 256 and the area of the circle is 200.96 you subtract 200.96 from 256 and you get 55.04 is the area of the square that is not covered by the circle. so 55.04/256  because that will give you the percent of the area that is outside that circle but inside the square and you get .215 or 21.50%
