303+202−75Step-by-step explanation:
The answer to this is 81x^2.
With area, you multiple two sides. With a square, all sides are equal and so, you just take 9x and multiply it by 9x.
9 x 9= 81
X x X= X^2
And so, the answer is 81x^2
Answer: See below
Step-by-step explanation:
Triangle ABC has vertices located at A( 0, 2), B (2, 5), and C (−1, 7)
A)

B) Slope of AB line = m₁=3/2
Slope of BC line = m₂=-2/3
Slope of CA line = m₃=-5
C) 
Therefore, the triangle is a isosceles right angle triangle
