A circular oil slick is expanding with radius, r in feet, at time t in hours given by r=12t−0.3t^22, for t in hours, 0≤t≤10. Find a formula for A=f(t), the area of the oil slick as a function of time.

its 4 because 2 times 2 is 4, if you double the number two you get four

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
