For this case we have that the area of the triangle is given by:

Where:
b: It's the base
h: It's the height
We have to:

The atura will be given by:

So, the area is:

Answer:
144
Step-by-step explanation:
The Midpoint Formula works exactly the same way. If you need to find the point that is exactly halfway between two given points, just average the x-values and the y-values.
14x45=630
43×2=86
(14×45)-(43×2)= 630-86=544
there would be 544 pens left
Answer:
From the points, the x coordinates are the same. With this similarity, the slope of the line would be undefined and it would result as an error to the point-slop formula of the line.
Answer:
35-7-7-7-7-7=0 also 35-7=28-7=21-7=14-7=7-7=0
Step-by-step explanation:
48-12-12-12-12=0 also 48-12=36-12=24-12=12-12=0
72-8-8-8-8-8-8-8-8-8=0 also 72-8=64-8=56-8=48-8=40-8=32-8=24-8=16-8=8-8=0
