Given the perimeter of a rectangle and either the length or width, find the unknown measurement using the appropriate formula. T
lions [1.4K]

Answer:

The measurement of the width is <u>20 ft</u>.

Step-by-step explanation:

Given:

The perimeter is 94 ft and the length is 27 ft.

Now, to find the unknown measurement.

Perimeter = 94 ft.

Length = 27 ft.

Let the width of the rectangle be x.

So, to get the width we put formula of perimeter:

Perimeter=2\times (length+width)

94=2\times (27+x)\\\\94=54+2x

<em>Subtracting both sides by 54 we get:</em>

<em />40=2x<em />

<em>Dividing both sides by 2 we get:</em>

20=x\\\\x=20\ ft.

Therefore, the measurement of the width is 20 ft.

Answer:

(2,9)

Step-by-step explanation:

The midpoint of a point is halfway between two points. The distance between the midpoint and point H is 3 because the distance from 5 to 8 is 3. Therefore 3 away from 5 would be 2.

Solve Morgan’s work to solve the equation. -8m + 6 - 2m = 9(3m + 4) + 5m
konstantin123 [22]
-8m + 6 - 2m = 9(3m + 4) +5m

-10m + 6 = 9(3m + 4) + 5m

-10m + 6 = 27m + 36 + 5m

-10m + 6 = 32m + 36

6 = 42m + 36

-30 = 42m 

-5/7 = m

m = -5/7

hope that helps, God bless!
