The unit for area is unit^2. You area for a rectangle is one of the easiest formula in math. A = LW
There’s a few ways to do this. But you essentially want to find the area for each rectangle and add them together.

We can do the two rectangles on the left, bedroom 1 and 3, by doing 3.5 x (4.25+3.75) = 31.5 in^2

Now do bedroom 2, we have to do 7.5 - 3.5 to get the width of the room since it wasn’t given directly. The width is 4 and we have the length of 3.5. Do 4 x 3.5 to get 14 in^2

31.5 + 14 = 45.5 in^2

We’re not done yet because they want it in ft^2 and we’re given 1 inch = 4 feet
Just do 45.5 x 4 to get 182 ft^2

Hello!

The five-number summary comprehends the minimum and maximum values, the 1st and 3rd quartiles and the median.

1st step: is to arrange the data sets from least to greatest.

Sherelle:

26 39 56 58 60 62 65 66 66 68 71 72 72 73 74 75 81 83 84 85

Venita:

44 45 51 51 53 53 55 57 58 62 65 66 69 69 70 73 75 77 78 79

2nd step: To calculate each quartile you have to determine their position and then identify which observation sits in that position:

Quartile 1:

PosQ₁: n/4= 20/4= 5

Quartile 2 (Median)

PosMe: n/2= 20/2= 10

Quartile 3

PosQ₃: n*(3/4)= 20*(3/4)= 15

Since both samples have the same size, the 1st quartile will be the fifth observation of each sample, the median will be the tenth observation and the 3rd quartile will be the fifteenth.

Sherelle:

Q₁: 60

Me: 68

Q₃: 74

Minimum: 26

Maximum: 85

Venita:

Q₁: 53

Me: 62

Q₃: 70

Minimum: 44

Maximum: 79

I hope this helps!

Answer:

6x+24

Step-by-step explanation:

6(3x+3) = 18x+18

-3(4x-2) = -12x+6
