Simplify the following expression: '5x - 8 + 3y + 10x - 8y'

monitta

Answer:

-5x-8-11y

Step-by-step

Because you shift 10x to -10x and then 5x-10x = -5x

You leave the -8 the same

You do 3y to -3y and then do -3y -8y = -11y

Hence altogether you get, -5x -8 -11y

At a campground, a rectangular fire pit is 7 feet by 6 feet. What is the area of the largest circular fire that can be made in t

Fittoniya [83]

The area of the circular fire pit is 4096 square inches.

Explanation:

Given that the rectangular fire pit is 7 feet by 6 feet.

We need to determine the area of the largest circular fire that can be made in this fire pit.

The diameter of the circular fire is 6 feet

The radius is given by

$r=\frac{6}{2} =3$

Radius is 3 feet.

The area of the largest circular fire pit can be determined using the formula,

$Area=\pi r^2$

Substituting the values in the formula, we have,

$Area = (3.14)(3)^2$

$=(3.14)(9)$

$Area= 28.26 \ ft^2$

We need to convert feet to inches by multiplying by 12, we get,

$Area = 28.26\times (12)^2$

$Area = 4096.44 \ in^2$

Rounding off to the nearest square inch, we get,

$Area= 4096 \ in^2$

Thus, the area of the circular fire pit is 4096 square inches.

I need help finding x.

amid [387]

Maybe using a protractor might help. But know that a straight angle equals 180. I don't really understand it. But use the <span>Pythagorean Theorem so a^2+B^2=c^2</span>
