Answer:
2x^2-4x-16
Step-by-step explanation:
Slope=rise/run
slope=(y2-y1)/(x2-x1) if you have the points
(x1,y1) and (x2,y2)
we have the points (-1,3) and (4,-7)
x1=-1
y1=3
x2=4
y2=-7
slope=(-7-3)/(4-(-1))=-10/5=-2
answer is D
90x0.15=13.5
so the total would be 103.08 before tax
You need to find the area of the hexagon, and the area of the triangle.
