Answer:
Step-by-step explanation:
xy = 42
x+y = - 2 Substitute into the top equation
y = -2 - x Put in for y
x(-2 - x) = 42 Remove the brackets
-2x - x^2 = 42 Subtract 42 from both sides.
-2x - x^2 - 42 = 0 Put in the more normal order.
-x^2 - 2x - 42 = 0 Multiply by -1
x^2 + 2x + 42 = 0
This cannot be factored. It gives complex roots as it is written. I will give you the answer but I kind of doubt the question is correct.
x1 = - 1 + 6.40i
x2 = -1 - 6.40i
Leave a comment if you have a correction.
It would quadruple.
Basically, it will quadruple because you are multiplying, which doesn't make much sense actually.
An example is with a 2 by 2 figure, you would get 4 squared as the area, but if you double both sides, 4 by 4, you would get 16 squared as the area.
It looks about 90 degrees
You divide 549/999, which makes 0.54954955
