Volume of a right prism = Area of the base * height
the base is the right triangle.
Area of a right triangle = ab/2
a = 15 inches ; b = 8 inches
Area of a right triangle = (15in * 8in)/2 = 120 in² / 2 = 60 in²
V = B * h
V = 60 in² * 10 in
V = 600 in³ Choice B.

A graph of this inequality would be a number line, with the number -2 circled (not filled in), and the number line to the right of -2 shaded.
To solve this, you will combine like terms first:
-3x-7x < 20
-10x < 20
Divide both sides by -10:
-10x/-10 < 20/-10
When you divide an inequality by a negative number, you flip the inequality symbol:
x > -2
