What is the area of the trapezoid? If necessary, round your answer to the nearest tenth. A trapezoid with bottom side length of
sveticcg [70]

Answer:

45.5 sq. feet

Step-by-step explanation:

Area of trapezoid is given by 1/2(sum of parallel sides) * height of trapezoid.

In the problem

Parallel sides are  bottom and top sides with  length of 8.5 feet and 5.5 feet

Thus sum of Parallel sides =  8.5 feet + 5.5 feet = 14 feet

Height =  6.5 feet.

Thus,

area of  trapezoid = 1/2*(14)* 6.5 feet = 7*6.5 feet = 45.5 sq. feet

Find the volume of rectangular prism if the length is 4X +3 with is X -6 and a height is 2X -1
cricket20 [7]

Answer: 8x³ - 46x² - 15x + 18

Step-by-step explanation:

To find the volume of a rectangular prism we will multiply each of the three dimensions given

First, let's multiply 4x+3 by x-6: (4x+3)(x-6) = 4x² - 21x - 18

Then we will multiply 4x²... by 2x-1: (4x²-21x-18)(2x-1) = 8x³ - 46x² - 15x + 18

a carpenter lays 16 squares feet of tiles in 1.5 of an hour.how many squares feet of tiles does the carpenter lay per hour?
lesya [120]
I believe that the answer is about 11 square feet because when you divide 16 by 1.5, you get 10.666666667, and most likely they won't be accepting an answer like that. So, you round to the nearest square feet and you get 11.
