the perimeter of a childs rectangular sandbox is 18 feet if the length of the sandbox is one foot longer than the width write an
equation that can find the length and width of the sandbox
1 answer:
Answer:
Equation:
Width = 4 feet
Length = 5 feet
Step-by-step explanation:
Let x feet be the width of the rectangle.
If the length of the sandbox is one foot longer than the width, then the length is x + 1 feet.
Use formula
The perimeter of a childs rectangular sandbox is 18 feet, thus
![18=2(x+(x+1))\\ \\18=2(x+x+1)\\ \\18=2(2x+1)\\ \\9=2x+1\ [\text{Divided by 2}]\\ \\2x+1-1=9-1\\ \\2x=8\\ \\x=4\ feet \\ \\x+1=5 \ feet](https://tex.z-dn.net/?f=18%3D2%28x%2B%28x%2B1%29%29%5C%5C%20%5C%5C18%3D2%28x%2Bx%2B1%29%5C%5C%20%5C%5C18%3D2%282x%2B1%29%5C%5C%20%5C%5C9%3D2x%2B1%5C%20%5B%5Ctext%7BDivided%20by%202%7D%5D%5C%5C%20%5C%5C2x%2B1-1%3D9-1%5C%5C%20%5C%5C2x%3D8%5C%5C%20%5C%5Cx%3D4%5C%20feet%20%5C%5C%20%5C%5Cx%2B1%3D5%20%5C%20feet)

Answer:
The distributive property here is to just multiply each value by tree number outside the parenthesis.
3 ( 4x - 2t)
12x - 6t
That would be your answer.
3(13-2a)=-3+a
39-6a=-3+a
42=7a
a=6
If it was 20 inches x 10 inches the perimeter would be 60 inches. which is the smallest possible perimeter with whole numbers
I think you should say you multipliyed?
