A cuboid with a volume of 924 cm^3 has dimensions
eduard

Answer:

21

Step-by-step explanation:

Volume of a cuboid is given by

V = l*w*h

924 = 4 (x+1) (x+11)

FOIL

924 = 4(x^2 +11x+x+11)

924 = 4(x^2+12x+11)

Divide each side by 4

231 = (x^2+12x+11)

Subtract 231 from each side

0 = x^2 +12x +11-231

0 = x^2 +12x - 220

Factor

0 = (x+22) (x-10)

Using the zero product property

x+22 =0  x-10 =0

x=-22  x=10

We cannot have a negative length

x=10

The side lengths are 4, 10+1, 10+11

4,11,21

The longest is 21

The function 2 ft t t ( ) 5 20 60    models the approximate height of an object t seconds after it is launched. How many sec
yaroslaw [1]

The function involves the initial speed of the object, and the height
from which it was launched, and whether it was launched upward
or downward.  As you can see, your post was corrupted and is
unreadable.  But when the object hits the ground, its height is zero. 
Set the function equal to zero, solve the quadratic equation that you
have, discard the negative solution, and the positive solution is your
answer.
