Simplify the expression below [-4x^2/5] [9x/5 ]

(-36 x^3)/25

Step-by-step explanation:

Simplify the following:

(-4×9 x^2 x)/(5×5)

Combine powers. (9 x (-4) x^2)/(5×5) = (9 x^(2 + 1) 4 (-1))/(5×5):

-(9×4 x^(2 + 1))/(5×5)

2 + 1 = 3:

((-9×4 x^3)/5)/5

9 (-4) = -36:

(-36 x^3)/(5×5)

5×5 = 25:

 (-36 x^3)/25

answer: it depends on what the tax percentage
