Which of the following would be a good name for the function that takes the weight of a box and returns the energy needed to lift it?

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}

Simplify the expression below -3(10x+4y)+6(6x-2y)
