3. Bricks are delivered to a work site and stacked in rows and columns, forming a rectangular prism. The length of the prism is

pychu [463]

Volume of a rectangular prism = 40 cubic feet.

Volume of a rectangular prism = length * width * height

width = x
length = 1 foot greater than its width = x + 1
height = 2 feet less than its width = x - 2

l * w * h = 40 ft³
(x+1) * x * (x -2) = 40
(x² + x)(x-2)
x³ - 2x² + x² + 2x = 40
x³ - x² + 2x - 40 = 0

solve for the value of x. I used the calculator to get the volume.

width = x = 4
length = x + 1 = 4 + 1 = 5
height = x - 2 = 4 - 2 = 2

V = 4 * 5 * 2
V = 20 * 2
V = 40 ft³

Find the perimeter of quadrilateral ABCD with vertices A=(1,1) B=(4,4) C=(7,1) D=(4,-2). Explain your answer.

Vanyuwa [196]

we have the coordinates of ABCD

there are 2 ways of doing this one is you find the distance of ab, bc, cd and da and then add the answers together. there is another way but i dont remember it properly so i am just gonna do it this way

distance between 2 point = $\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}$
