The area of a rectangular floor is 8x+6x-20. The width of the desktop is 2x+4. What is the length of the floor?
Answered by jinie
was the 8x suppose to be 8x^2??
Answered by jinie
if it is then the length would be 4x-5
you just factor it out of the 8x^2+6x-20 since they already give you the other factor which is 2x+4
