A cube has the volume of 7 units. What is the edge length of the cube?

Given δjkl : δxyz, find x. a)10 b)12 c)16 d)20

Write the component forms of vectors u and v, shown in the graph, and find v − 2u. u= (< -3, -2> , < -3, -1> , < -2, -2> , < -2, -1> ) v= (< -5, 1> , -4, 0> , < 0, -4> , < 1, -5> ) v-2u= (< 5, 3> , < 0, 4> , < 4, 0> , < 5, -3>

Which shows one way to determine the facts of x3+4x2+5x+20 by grouping
