Let u = {q, r, s, t, u, v, w, x, y, z} a = {q, s, u, w, y} b = {q, s, y, z} c = {v, w, x, y, z}. list the elements in the set. a ∩ (b ∪ c)a) {q, s, w, y}b) {q, y, z}c) {q, s, u, w, y, z}d) {q, r, w, y, z}

  a) {q, s, w, y}

Step-by-step explanation:

B ∪ C = {q, s, y, z} ∪ {v, w, x, y, z} = {q, s, v, w, x, y, z} . . . . elements in either set

A ∩ (B ∪ C) = {q, s, u, w, y} ∩ {q, s, v, w, x, y, z} = {q, s, w, y} . . . . elements in both sets (matches selection A)

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2
