While visiting the beach, Dan used a pyramid shaped mold to create a sandcastle. The base of the mold was a rectangle measuring 11 in. By 7 in. The height of the mold was 8 in what is the volume of the sand that the mold will hold?

Use the net as an aid to compute the surface area of the triangular prism. a) 550 m2 b) 614 m2 c) 670 m2 d) 790 m2

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =

If y varies directly as x2 and y=6 when x=6, find the constant of variation.
