1 answer:

4 0

Distribute
(7x)(4x^2-3x-6)+(-3)(4x^2-3x-6)=
28x^3-21x^2-42x-12x^2+9x+18=
28x^3-21x^2-12x^2-42x+9x+18=
28x^3-33x^2-33x+18

D is the correct answer

Well, if the notebooks cost x, then you know that
3x + 45.87 = 60.54
right? so, solve for x. 60.54 - 45.87 = 14.67
Divide the difference by 3.

Answer:

Slope-Intercept form: y = m x + b

y = value of y corresponding to value of x

2 y = 10 x - 6

y = 5 x - 3 equation of line where m is the slope and -3 value of y when x

equals zero

Put the 116 on top of 200 and simplify. You will need to simplify by 4 which will get you 29 over 50.
