If there is a photo that is 4 by 9 inches, and you want to frame it with a frame the same width all around, and the total area of the photo and the frame is 130², how wide is the frame?

boxplot

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
