For which of the following pairs of sets is it true that n(D) + n(E) = n(DUE)? a. D = {1, 2, 3, 4), E = {5, 6, 7, 8}
b. D = {}, E = {1}
c. D = {a, b, c, e), E = {c, b, a, d}

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

answer: the correct answer is -32
