A (-3, -1)
You know this because QIII is in the bottom left corner and both numbers are negative
Answer:
no solution
Step-by-step explanation:
when you substitute 
for 
the equation is false
how I solved this:
1. substitute for
2. distribute the 3
3. combine like terms
this is incorrect because 12 does not equal -12, so there is no solution
The maximal area obtainable if we assume that the
farmer builds a field in the shape of an isosceles triangle, where the two
equal sides are the fenced sides, and the third side is the river is determined
using the same formula used in getting the area of an isosceles triangle.
THE FORMULA
Multiply the base
(length of the side of the river) and the height of the triable at its tallest
point, then divide the product in half.
A = 1/2 x b x h, where b is the base, and h is the height.

120*3=360. That's the answer.
