A cube is a rectangular solid box with a height (h), length (l), and width (w). The volume is h x l x w and the surface area is 2lw x 2wh + 2lh.

The first step to solve a quadratic equation that's set to zero is to factor the quadratic equation:

y² + 10y + 24 = 0
(y + 4)(y + 6) = 0

For this expression to be true, the left side of the expression must equal zero. Therefore, either (y + 4) or (y + 6) must equal zero:

If (y + 4) = 0, y must equal -4
If (y + 6) = 0, y must equal -6

So the solution is that y = -4 or -6

A parallelogram is a quadrilateral with two sets of parallel sides. Opposite sides (a = c, b = d) and angles (red = red, blue = blue) are equal. The area of a parallelogram is base x height and the perimeter is the sum of the lengths of all sides (a + b + c + d).

To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses.

An isosceles triangle has two sides of equal length. An equilateral triangle has three sides of equal length. In a right triangle, two sides meet at a right angle.
