Answer:
D
Step-by-step explanation:
I'm assuming you're looking for area here.
The formula is b * h = A
So all you're doing is multiplying 30 by 18 to get 540.
Answer: x=5, y=22 C.
Step-by-step explanation:
I just did the quiz
3 cm on the map represents 31.5 km in reality.
3cm : 31.5 km
1cm : 31.5/3 km
1cm : 10.5km
So the scale on the map is 1cm represents 10.5 km.
Y=12x
Check: 72=12(6)
72=72
y=12x
y=12(10)
y=120
when x is 10 y is 120
