What is (x^2- 5x-4) (-2x+4) simplified

=-2x^3 + 14x^2 - 12x - 16

Step-by-step explanation:

=(x^2 + -5x + -4)(-2x + 4)

=(x^2)(-2x) + (x^2)(4) + (-5x)(-2x) + (-5x)(4) + (-4)(-2x) + (-4)(4)

=-2x^3 + 14x^2 + 10x^2 - 20x + 8x - 16

=2x^3 + 14x^2 - 12x - 16

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
