Can someone help me please

Hello!

First things first, lets find the Length and width of the rectangle.

So the length is given and is : 18ft and 4 in long

And the width is: 10 ft and 6in long

Next lets convert ft to inches and rewrite the length and width.

There are 12 inches in a foot right?

for multiply 12 by the given feet.

--------------

To find the length in inches:

18 times 12 = 216

216 + 4

220 inches

--------------

To find the length in inches:

10 times 12 = 120

120 + 6

126 inches

--------------

Okay, we now have the basic info!

A) 692 inches

We are finding the perimeter of the rectangle:

The formula for perimeter is 2L + 2W

Let plug that in: 2(220) + 2(126) = 692inches

-----------------

B) 27,720 inches squared

We are finding the area of this rectangle:

The formula for Area is L*W

Lets plug that in: (220)(126) = 27,720 inches squared

-----------------

-------------------------

11.

Yes, you are on the right track!

Now you need to find a number that you convert all of the fractions to.

Lets make the common denominator 10!

Multiply the denominator and numerator by factors that equal ten of the following mixed numbers.

You'll get:

the /4 means divide by 4.

So now you are going to find the mean. by adding all those numbers up and dividing it by the amount of numbers there are (4).

(108/10)/4

Mean is above

-----------------

Median:

My work didn't save but the median is 57//20

which is reduced to 2 17/20

answer: c i think

step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
