The answer would be
-3 ≤ x ≤ 5
Answer: 480. Hope it helps! :)
Step-by-step explanation:first, you times 10 times 8, you get 80. then, you times it by six. Your answer is 480.
If x represents the length of the box, then 42-x will be the girth. Since the largest area for a given girth is that of a square, the side length of the square cross section is (42 -x)/4.
The volume as a function of package length is then
.. v(x) = x((42-x)/4)^2
This has a maximum at x=14. The corresponding volume is 686 in^3.
Step-by-step explanation:
(x+2y)²=x²+4xy+4y²

Total no. of buttons = 300 + 700 + 1000
+ 500 = 2500
Possibility for a person to pick a pink button = 300/2500 = (3/25)%
Amount of pink buttons she can expect her friends to pick = 50(3/25) = 6
She can expect to make 6 pink barrettes.
