you are making a fence of your garden the length is five less than two times the width write a polynomial that represents the perimeter of the garden write a polynomial that represents the area of the garden
Now you can take the time to reread and understand the question.
What is the length if the width is x?
Take the sentence
"length is five less than two times the width" and replace the word "width" by x (that we defined above), and translate it to mathematics.
Put x = width of the garden
then what would be the length in terms of x?
