Answer:
Step-by-step explanation:
5*5*5*2

I suppose you could use 2P1 for that.
5 * 5 * 5 * 2P1
Answer:
equal to
Step-by-step explanation:
A circle with a diameter of 2x has a radius of x, so will have the same area as a circle with a radius of x.
Distance=amount of gas times miles per gallon
distance=y
amount of gas=x
mpg=?
given
y=300
x=10
300=10 times ?
divide both sidesj by 10
30=?
equation is
y=x times 30 or
y=30x
