Problema Solution
The width of the bedroom is (x-5) feet. The length is 4 times the width. Write an expression for the perimeter of the bedroom.
The area of a rectangle is 2x^3-7x^2-17x-3 and the width is 2x+3. Write a polynomial to express the length.
Answer provided by our tutors
perimeter = 2*length + 2*width
Let 'P' represent the perimeter, the width is 'x-5' and the length is '4(x-5)':
P=2(x-5)+2*4*(x-5)
P=10x-50
The perimeter of the bedroom is '10x-50'.
