Answer:

the coefficient of the 2nd term: - 38

Step-by-step explanation:

V = 2x (4x + 1) (5x - 6)

   =(8x² + 2x) (5x - 6)

   = 40x³ - <u>38</u> x² - 12x

Guys I am going to run out of points. Help with 19?<br> I don't need an explanation.

Answer:

A.) 20x + 2y = 500

B.) y-intercept = 250; its meaning is how many boxes of pencils they started with.

C.) x-intercept = 25; How many T-shirts they can sell at most

Step-by-step explanation:

2y - 500 = -20x

20x + 2y - 500 = 0

20x + 2y = 500

y-intercept = 250; its meaning is how many boxes of pencils they started with.

20x + 2y = 500

20(0) + 2y = 500

2y = 500

2y/2 = 500/2

y = 250

x-intercept = 25; How many T-shirts they can sell at most

20x + 2y = 500

20x + 2(0) = 500

20x = 500

20x/20 = 500/20

x = 25
