Solve the following problems involving applications of polynomials.
a. A photo is 3 inches longer that it is wide. A 2-inch border is placed around the photo making the total area of the photo and border 108 square inches. What are the dimensions of the photo?
b. A rectangular parking lot is 100 ft longer than it is wide. Determine the dimensions of the parking lot if it measures 500 ft diagonally.
c. Three consecutive odd integers are such that the square of the third is 264 more than the square of the second. Find the three integers.

a.) Same as GEOMETRY PROBLEM #151709
SEE ANSWER# -------> DONE.
b.)The is 100ft longer than the --->
The side given = 500ft, by PYTHAGOREAN THEOREM:
, but , so

---> , Divide the whole eqn by 2:

---> ,, &
By Pyth. theorem:

------>
2 values:
----------> TO BE USED ---->
--------> DO NOT USE
So,
To check, go back PYTH Theorem:
, good!
.
3.) Let = 1st odd integer
= 2nd odd integer
= 3rd integer
condition: square of 3rd is 264 more than suqrae of 2nd: to show,

-->
-----------------------> 1st odd integer
--------------------> 2nd odd integer
--------------------> 3rd odd integer
in doubt? go back to the condition:

Thank you,
