Sarah fenced in her backyard. the perimeter of the yard is 18 feet, and the width of the yard is 4 feet. use the perimeter formula to find the length of the rectangular yard in inches: p = 2l + 2w.

  60 inches

Step-by-step explanation:

Fill in the given numbers and solve for length. Then convert to inches.

  18 ft = 2L +2(4 ft)

  10 ft = 2L . . . . . . . . subtract 8 ft

  5 ft = L = 5×(12 in) = 60 in

The length of Sarah's back yard is 60 inches.

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !

you should talk someone who owns the website about it. you did not deserve to have all that hard work and time taken away. id watch videos of little puppies to cool you down, and maybe some nacho cheese doritos.
