Answer:-3x+12
Step-by-step explanation:
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:

Answer:
2nd one
Step-by-step explanation:
Answer:
23
Step-by-step explanation:
F=(9/5)c + 32
F=(9/5)(-5) + 32
F=(-9) + 32
F=23
