Algebra 2

i actually have two questions.

- the edge of one cube is 4 m shorter than the edge of a second cube. the volumes of the two cubes differ by 1216m^3. find the edge of the smaller cube.

- the sum of the squares of the two larger of three consecutive even integers is 12 less than 4 times the square of the smaller one. find the intergers

Please and Thank-you(:

  • Algebra 2 -

    1. Let x = side of the smaller cube and x+4 = side of other. Then

    (x+4)^3 - (x^3) = 1216

    Solve for x.

    2. If x = smallest even integer, x+2 = next and x+4 = largest

    (x+2)^2 + (x+4)^2 = 4x^2 - 12

    Solve for x.
