A print of a square photograph has a 2-inch white mat on the left and right sides, and a 3-inch white mat on the top and bottom. The area of the print, including the mats, is 143 sq. in. Write an equation that summarizes the known information about the area of the print. Rewrite the equation as a quadratic equation in standard form.
Solve by factoring
What are the dimensions of the print with the mats? What are the dimensions of the photo?

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
