A cubed-shaped box has its side lengths decreased by 3 cm, when this happens, the volume decreases by 1385cm^3. What is the side

mixer [17]

Answer:

Step-by-step explanation:

let side of cube=x cm

volume=x³ cm³

again side=(x-3) cm

volume=(x-3)³ cm³

x³-(x-3)³=1385

(a³-b³)=(a-b)(a²+ab+b²)

(x-x+3){x²+x(x-3)+(x-3)²}=1385

3(x^2+x²-3x+x²-6x+9)=1385

3(3x²-9x+9)=1385

9x²-27x+27=1385

9x²-27x+27-1385=0

9x²-27x-1358=0

$x=\frac{27\pm\sqrt{(-27)^2-4*9*(-1358)} }{2*9} \\x=\frac{27\pm\sqrt{729+48888} }{18} \\or~x=\frac{27\pm\sqrt{49617} }{18} \\or~x=\frac{27\pm 222.749}{18} \\taking positive side only as negative sign gives negative length.\\or~x=\frac{27+222.749}{18} \\or~x\approx13.87$

Please answer this correctly

MAVERICK [17]

Answer:

1:50 PM

Step-by-step explanation:

Left school at 10:38 AM,

took them 51 minutes,

38+51=89,

89-60=29,

so when they drove to the museum, it was 11:29 AM.

From here, they stayed at the museum for 1 hour and 26 minutes,

so they stayed at the museum until 12:55 AM since 29+26=55.

Now, it took them 55 minutes to drive back to the school,

so 12:55 plus another 55 minutes,

it's going to be 1:50 PM when Dale's class got back to school.
