You have 2+2 in each 2 there are 1's so
2=(1+1) 2=(1+1) =4
4=1+1+1+1
2+2=4
think of 2's as 1's when adding did you know 2x2= 4 as well.
The answer is going to be 12.9 and the median height will be 16.5 hope that helped
The formula of a midpoint of AB:

We have:
G(b; 0); F(3b; 2b)
substitute:

Answer: (2b, b)
X is 90 degrees. If AB is the diameter, then it passes through the centre. X is 90 degrees because the angle in a semicircle is always a right angle.
Answer:
the figure could be a rhombus because the 2 lines of symmetry bisect the angles
