Answer:

Step-by-step explanation:
I assume that the three points given are the vertices of the triangle. So the three points are:
A (-4,1)
B (-7,5)
C (0,1)
The area of a triangle is given by:

where b is the base and h is the height.
Here we can take as follows:
- We can take the base to be the side AC, so that its length is equal to the distance between the two points:

- The height of the triangle is therefore the perpendicular distance between AC and point B. This is equivalent the difference in the x-coordinate between any point on AC and B, so:

Therefore, the area of the triangle is:

I would try Khan Academy. He does very good explainations
300-30.3=269.7 because you barrow from 3 in 300 because you can't round into 0 and that equalled 7 and than you do 9-0=9 and there's 009.7 than you do 9-3=6 and that's 069.7 and you do 2-0=2 and there's 269.7
Answer: -10
Step-by-step explanation:
It is -10 because you have to switch the order of operations to get negative.

Answer:
Hello,
16
Step-by-step explanation:





2 x 1 = 2
2 x 2 = 4
2 x 4 = 8
2 x 8 = 16
2/1 = 4/2 = 8/4 = 16/8 = 2
