Answer: x times (x-4)=45

Step-by-step explanation:

First since the area is 45 that’s what the equation has to be equal to.
To find the area you always have to do length times width. So the width (x) times the length (x-4) equals 45.

Add the equations together so that you get 6x=-4, how I got their is cancel out the +/-3 and then add the -10+6=-4. Then you’d bring over the 6 and it would look like this x=-4/6 which you would simplify by dividing 2 into the 4 and 6 and should look like this x=-2/3
