Answer:
Step-by-step explanation:
Polynomials are factored after they are set equal to 0. This i because the factors of the polynomial are also known as the x-intercepts, and x-intercepts exist where y = 0. Therefore, if the factors of the polynomial are
(x + 8)(x + 4) = 0, then by the Zero Product Property,
x + 8 = 0 so x = -8 or
x + 4 = 0 so x = -4. Choice A.
Answer:
x = -2
Step-by-step explanation:
Answer:
20 x 30 = 600
3,600/600=6
Check if it works
20 x 30 = 600
600 x 6 = 3,600
the missing width is 6
Step-by-step explanation:
The empty set (or null set) is a subset of every set.
