1:2...added = 3
1/3(18) = 18/3 = 6 (yellow chalk)
2/3(18) = 36/3 = 12 (not yellow)
so 6 pieces are yellow and 12 pieces are not

Answer:
x = - 2 or x = 4
Step-by-step explanation:
To find the x- intercepts let f(x) = 0, that is
(x - 4)(x + 2) = 0
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 2 = 0 ⇒ x = - 2
The x- intercepts are at x = - 2, x = 4
