Let x = the width
then
2x = the length
:
The box dimensions: 2x by x by 4
Given the surface area:
2(2x*x) + 2(2x*4) + 2(x*4) = 220
:
4x^2 + 16x + 8x = 220
A quadratic equation:
4x^2 + 24x - 220 = 0
simplify, divide by 4
x^2 + 6x - 55 = 0
Factor
(x+11)(x-5) = 0
The positive solution is what we want here:
x = 5 ft is the width
then
2(5) = 10 ft is the length
:
Find the volume
10 * 5 * 4 = 200 cu/ft is the volume

Answer:
Step-by-step explanation:
the polynomial function is; (x - i)(x-2)(x+2)
Answer:
39.9 grees
Step-by-step explanation:
Since 4.2 kribs = 18 grees
Then,
1 krib = 18/4.2 grees
9.3 kribs = (18/4.2) x 9 3
9.3 kribs = 39.9 grees.
