Question 74838: I need to convert this into a quadratic equation. I can get the correct answer, I just can't figure out how to write a quadratic equation that works.
1. A designer, attempting to arrange the characters of his artwork in the form of a square grid with equal number of rows and columns, found that 24 characters were left out. When he tried to add one more row and column, he found that he was short of 25 characters. Can you find the number of characters used by the designer?

Question 75093: 30A garden area is 30 feet long qand 20 feet wide. A path of uniform width is set around the edge. If the remaining garden is 400 square feet, what is the width of the path?
30 * 20 = 600
600-400 =200
lw=Area
lw= 200
I drew a picture and still really did not make sense. If I could figure out how to use the quadratic to solve this I could easily do the actual math, but I am struggling setting up the equation.

Question 75706: I have worked through this problem and end up with a different answer. I am not understanding how to reduce the sqrt, everything I have done to this point matched the solver. I do not want the decimal form, it needs to remain in sqrt. This not from a text book, it is practice for a placement exam.
2+ or - sqrt of 20
x= __________________
2
I imagine there is a better way to type this out for you, but I don't know it...sorry.
Truly,
Shelly
