Kenley Whitaker · Answer 1

15x2 - 62x + 40

Step-by-step explanation:

(10 - 3x) (4 - 5x) = 10 x 4 + 10 x - 5x - 3x x 4 - 3x x - 5x = 15x2 - 62x + 40

f (x) is a parabola, now you have to graph

x=10/-3, 4/5

Step-by-step explanation:

f (x) = (10 - 3x) (4 - 5x)

10-3x=0

-3x=-10

x=10/3

4 - 5x = 0

-5x = - 4

x = 4/5
