Answer:
2 percent
Step-by-step explanation:
We can use two separate fractions, one representing the amount of physics majors expected and the amount of seniors expected in physics majors by the university.
Now cross multiply.
x will be removed.
Simplifying this fraction will get you 
, which in percentage form, will be 2 percent.
Red die: 1,2,3,4
green die: 4,3,2,1
I'm not sure if that's the answer you were looking for, but hopefully that helps.
<span>The nonpermissible replacement for the variable x in this expression is x = 2
Substituting x = 2 yields:
(2)^2/(2(2)-4)
4/0, which is undefined.

Answer:
x^3+9x^2-3x^2-3
Step-by-step explanation:
You can use a various of methods but when you use the box method you multiply each separately.
Like you would multiply x² by x, 8x by x, -3 by x (thats the first row)
x² by 1, 8x by 1, -3 by 1 ( for the second row)
Then you get those final variables and combine like terms getting the answer above
4k(3n+2) this is basically just factoring out a common multiple which in this case is a k and a 4
