Answer:
Area = 21/2 = 10.5 area units
Step-by-step explanation:
Two of the points are on the same line (the y-axis) as they both have x-coordinates of 0. This can thus be the base of your triangle.
Two more are on the same line (y= -9) as they both have the same y-coordinate of -9. This can be the height of your triangle.
So you have a base which is between -2 and -9 (7 units) and a height which is between 0 and 3 (3 units) so now just use the equation for area of a triangle

Answer: 1) The missing length is 40. 2) The missing side is 30 .
Step-by-step explanation:
1) 9^2 + b^2 = 41^2
81 + b^2 = 1681
-81 -81
b^2 = 1600
b= 40
2) 24^2 + 18^2 = c^2
576 + 324 = c^2
900 =c^2
c= 30
I have a simple but slightly time consuming way of doing this. Find 30% of 100 double it and then find 30% of 25, add the two together... In this case 60 + 7.5. After you do that subtract that number from 225. So subtract 67.5 from 225 and there is your answer. Your answer is 157.5
The answer for the equation is -1
