A family is having a pool built in their backyard. Their yard is rectangular and measures 14x by 19x and the pool is circular wi

valentina_108 [34]

You want to find the area left over after the pool is built, so subtract the area of the pool from the area of the yard.

Area of Yard= Base x Height = 14x*19x = 266x^2
Area of Circle= Pi x Radius^2 = (6x)^2*pi = 36x^2*pi

Now subtract the two areas:
266x^2-(36^2*pi)
266x^2-36x^2*pi

Take 2x^2 as a common factor:
2x^2(133-18pi)

D: 2x^2(133-18pi)

Hope this helps :)

Answer: Delete the point (0, 4)

Step-by-step explanation:

Your line for y = (1/3)x + 4 is correct.

m=1/3 b=4

Start at (0, 4) and draw a line through a point up 1 and 3 to the right (3, 5).

Your line for x = 6 is correct.

A vertical line through (6, 0), (6, 1), (6, 2), ...

Your point for (6, 6) is correct.

x=6, y=6

Your error is that you used the dot tool to plot a point for (0, 4). You DO need this point to create the line y = (1/3)x + 4, however the instructions do not state to mark this coordinate with a dot.

If the area of a rectangle is 144 sq. in. and the length of one side is 18in. what is the length of the other side?

navik [9.2K]

Hello from MrBillDoesMath!

Answer: The other side has a length of 8

Discussion:

Area of a rectangle = l * w ( length times width). In our case

Area = 144 = l * w = 18 * w =>

18 w = 144 =>

w = 144/18 = 8

Thank you,

MrB
