Answer:
x=3 and x=-2 is the root of given eq
To find the area, you of course multiply your length by width (40 x 20), which would get you your area of 800 ft squared. hope this helps!
It would be perpendicular expression
The freezing point of water is 32F and 0c.
This is one half of a simultaneous equation. Without the other half, the values are theoretically unsolvable.
With that said, with trial and error you can work this out. I came out with an answer of x=1, y=12.
This is not a good practice. It's time consuming to solve simultaneous questions like this. Make sure you use the other half of the equation in the future.
I hope this helps!
