Answer:
l = 3x+5
Step-by-step explanation:
Area Formula:
A= lw
Given Area:
6x^2+19x+15
Given width:
2x+3
Using these values for A and w, rewrite the area formula:
6x^2+19x+15= l (2x+3)
Factor left side to see ita component polynomial factors:
(3x+5)(2x+3)= l (2x+3)
Now bot side of the equation have a common binomial factor. Devide it from each side:
The result is:
l=(3x+5)
