<span>B. Carbon dioxide gas in air </span>
<u>Solution:</u> 48cm/s^2
<u>Working:</u>
A = s^2
Derivate s^2 (as it is area formula) which gives
dA/dt = 2s dL/dt
dL/dt = 6cm/s
Hence,
2(6) = 12
Side: 4cm
Hence,
dA/dt = (4)(12) = 48cm/s^2
<em>Feel free to mark this as brainliest :D</em>
3x=18 because you add the like terms 6 and 12
Answer:
120
Step-by-step explanation:
Exterior angle theorem
