Answer:
Length = 12
Width = 8
Height = 4
Step-by-step explanation:
Let length of box = l
Width = 2/3 * l
Height = 1/3 * l
Volume of the box = 384 ft³
Volume = Length * width * height
Volume of box = l * 2/3 l * 1/3 l
384 = 2l³ / 9
384 * 9 = 2l³
3456 = 2l³
l³ = 3456 / 2
l³ = 1728
Take the Cube root of 1728
l = 12
Length = 12
Width = 2/3 * 12 = 8
Height = 1/3 * 12 = 4
B. is the only correct choice of those listed

Answer:
(-12, 2).
Step-by-step explanation:
x^2 + 10x = 24
Divide the + 10 by 2 to give the following identity:
x^2 + 10x is equivalent to (x + 5)^2 - 25 so:
(x + 5)^2 - 25 = 24
(x + 5)^2 = 49
Taking square roots:
x + 5 = +/- 7.
x = -5 + 7 = 2
and x = -5 - 7 = -12.
