In △NMP, m∠MNP = 45°, MN = 7.5 feet, and MP = 5 feet. How many triangles can be drawn when given the information above?
More than one triangle; Sample answer: If two sides and a nonincluded angle are given, two triangles can be drawn, and side NP can be two different lengths.
The height of the rectangular prism measures 64 cm. The base is 42 cm x 35 cm. If the height is increased by 1.5 cm, by how much will the surface area of the box increase?

The diameter of Circle J is 18 cm. The diameter of Circle K is 31 cm. Which circle has the greater area and by how much? Use 3.14 for pi.
The area of Circle K is about 500 cm2 greater than the area of Circle J.
explain why there can be two vertical cross-sections for a right rectangular prism but only one horizontal cross-section when the slices are made parallel to a side.
There is only one horizontal cross section because there is only one dimension that can be sliced horizontally, the height. There are two vertical cross sections because there are two dimensions that can be sliced vertically, the length and the width.
