Atriangle has a base length of 14cm greater than its height . if the area of the triangle is 48cm^2, find the height of the triangle .

Me find the missing dimension of a triangle height: 7 in., area: 21^2

3x + 4y = 5 x- 3y = -7 solve by substitution

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}
