B because the square root of 39 is 6.24499799...
<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

Step-by-step explanation:
x2 + 7x + 12
x2 + 4x + 3x + 12
x(x + 4) + 3( x + 4)
(x + 3) and (x + 4) are the factors
4x2 + 6x + 2
4x2 + 4x + 2x + 2
4x (x + 1) + 2(x + 1)
(x + 1) and (4x + 2) are the factors
