Joe has $20 to spend on two model cars and supplies to paint them. The paint supplies cost $4.00 Which expression shows how much he can spend on each model? A. x ≤ $8
B. x ≥ $8
C. x ≤ $16
D. x ≥ $16

Step-by-step explanation:

He can spend x dollars on each model and 2x on both:

Correct choice is A.

you have 6 cupcakes

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
