Answer: B
Step-by-step explanation:
It is 23a+72
see
6(-3a+12)+8a-13a
-18a+72+8a-13a
23a+72
do you understand
Ok lol I was going to put 180 but if you got it than that’s fine.
Answer: Choice C) 10.5
The distance from A to C is 7 units (count out the spaces between the two points, or subtract y coordinates 4-(-3) = 4+3 = 7)
Let AC = 7 be the base of the triangle. You might want to rotate the image so that AC is laying horizontally rather than being vertical.
Now move to point P. Walk 3 spaces to the right until you land on segment AC. This shows that the height of the triangle is 3 when the base is AC = 7.
base = 7, height = 3
area of triangle = (1/2)*base*height
area of triangle = 0.5*7*3
area of triangle = 10.5 square units
5 multiply by 8=40
40 divided by 20=2
So each person gets 2 slices of pizza
