$f(x)=3x-23,\ g(x)=-4.5x+7\\\\f(x)=g(x)\iff3x-23=-4.5x+7\qquad\text{add 23 to both sides}\\\\3x=-4.5x+30\qquad\text{add 4.5x to both sides}\\\\7.5x=30\qquad\text{divide both sides by 7.5}\\\\\boxed{x=4}$

What is the volume of a frustum of a rectangular pyramid if one base has measurements 6 ft. × 8 ft., the other base has measurem

RoseWind [281]

To solve this, we use the formula for the volume of the frustum of a cone which is expressed as:

V= (H/6)[WL + (W+a)(L+b) + ab]
V = 3/6 [(6 ft. × 8 ft.) + (6 + 14)(18 + 8) + (14 ft. × 18 ft.)]
V = 409.98 ft^3 <-----OPTION C
