Answer:
37.7 mi²/h
Step-by-step explanation:
The area formula is ...
A = πr²
Differentiating with respect to time gives ...
dA/dt = 2πr·dr/dt
Filling in the given values, we have ...
dA/dt = 2π(3 mi)(2 mi/h) = 12π mi²/h
The area is increasing at the rate of about 37.7 mi² per hour.

Answer:
x = -5
Step-by-step explanation:
2x-3+3x= -28
combine like terms
5x -3 = -28
add 3 to each side
5x-3+3 = -28+3
5x = -25
divide each side by 5
5x/5 = -25/5
x = -5
You can change the denominators so they are alike.

Not sure how there can be two possible answers unless you're mentioning the decimal form:
.775
