I posted this the other day but no one responeded. Yes, I am looking for the steps and a answer because I can not get it.

Question: Area of Painting: A rectangular painting with a width of x centimeters has an area X^2 +50x square centimeters. Find a binomial that represents the length.

X^2 +50x factors and
= x(x + 50)

clearly, x must be a positive number, so clearly x+50 is larger than x

Usually, in talking about length and width, the length is the larger of the two dimensions, isn't it ?

So, what do you think?

To be honest, I could not figure out this problem. I don't know why I am so confused..

Area = width x length
X^2 +50x = x(x+50)

so x must be the width
x+50 must be the length
