Question 285446: Area of a painting. A rectangular painting with a width of
x centimeters has an area of x2 + 50x square centimeters.
Find a binomial that represents the length.
So what I have is that:
A=lxwxh
w=x
In this problem:
A=x^2 + 50x^2
I am guessing the following:
LxXxH=x^2+50x^2

Area of a painting. A rectangular painting with a width of
x centimeters has an area of x2 + 50x square centimeters.
Find a binomial that represents the length.
======================
Area = width*length
---
Substitute and solve for "length":
x^2+50x = x(length)
------
length = (x^2+50x)/x
----
length = x + 50
======================
