The answer is C.
Point G can be centroid because 12:6 equals 2:1
FG = 6
FC = 18
so
GC = 12
12:6 = 2:1
21 because a triangle is always going to equal 180 so add those then subtract and it’s 21
Draw a bar and draw little squares inside the box not the bar and then shade the boxes this will represent the number
If you would like to calculate 6/(x+1)-5/2=6/(3x+3), you can do this using the following steps:
6/(x+1)-5/2=6/(3x+3)
6/(x+1)-5/2=6/(3(x+1)) /*(x+1)
6 - 5/2 * (x+1) = 6/3
6 - 2 = 5/2 * (x+1)
4 = 5/2 * (x+1) /*2/5
4 * 2/5 = x + 1
8/5 - 1 = x
x = 8/5 - 5/5 = 3/5
The correct result would be 3/5.
