Answer:
A. 45 in
Step-by-step explanation:
To find area you multiply length and width so you would multiply 9 and 10 but since it is a triangle you would divide by two
Hope this helps!
Construct the line using the two points:
slope: m = (-4 - 2) / (4 + 3) = -6/7;
then, y = mx + b => 2 = (-6/7)(-3) + b => 14/7 - 18/7 = b => b = -4/7.
And your y-intersect is -4/7.
Length: 2x-1, width: x
A=LW
120=x(2x-1) 120=2x^2-x 0=2x^2-x-120, Factor (x-8)(2x+15)=0
x=8 is the width and 15 is the length

Aha! Now we have a path to the solution!
We can test random values for 
, such as 
, 
, or even 
.
This leads us to drawing lines.
Answer: We draw the line 
(equivalent of testing out random points), and where it intersects the graph of ! is our answer!
(Note: it can only intersect once, otherwise it would fail the vertical line test and wouldn't be a function)
