the zero product property would say that you can set each equal to 0 then solve for x.
A you actually have wrong. It should be (x+45)(x-40)=0. this would give you the positive 5x in the equation.
(x+45)=0 and (x-40)=0
solve for x for both
x=-45 and x=40
C. This means that x could equal -45 and 40, and the equation would be true
you can plug the numbers in to check
this is a true statement.
40 should work as well if you plug it in

wait what do i write for b?
is this correct?
you showed it correctly, but used the wrong equation. your answer the A is wrong. My first reply explained why. you should end up with x=-45 and x=40
the equation for the length can be written as l=2w+10, where w is the width.since the width can't be a negative number, it has to be 40. so the length can be found by plugging 40 into w.
and you know this is correct because the total area of the dog park is 3600.
you now know the length is 90 and the width is 40
which is true
