Answer:
The Answer is (A)
Step-by-step explanation:
A sample of each symbol (point, line, or area), and a short description of what the symbol means
Areaa= 0.5 b h
= 0.5 x 9 x 6 = 27 mm
B is the only rational answer.
3/8y = 9/24 since 3*3=9 and 8*3=24
4 = 64/16 since 16*4=64
3z/x = 9z/3x since 3z*3=9z and x*3=3x
