-10x -120-11x
combine like terms so -10-11= -21x-120

Step-by-step explanation:
Answer:
Area of triangle = 20√2
Step-by-step explanation:
Formula:
Area of triangle = bh/2
b - base of triangle
h - height of triangle
Distance formula
d = √(x₂ - x₁)² +(y₂ - y₁)²
From the figure we can see that, the given triangle is right angled triangle.
Base = AC and Height = AB
<u>To find AB and AC</u>
A(1,3), B(4,7) and C(9, -5)
AB = √(4 - 1)² +(7 - 3)² = √(3² + 4²) = 5
AC = √(9 - 1)² +(-5 - 3)² = √(8² + -8²) = 8√2
<u>To find the are of triangle</u>
Area = bh/2 = (5* 8√2)/2 = 20√2
First identify the a, b, c of the quadratic:
A= -2, B= 0, and C= 3
There’s no b value since there’s no x term, just a constant and an x^2
The square root of (0)^2-4(-2)(3) is equal to 24
