Answer:
no
Step-by-step explanation:
2 - 2 = 0, not a positive integer.
2 - 3 = -1, a negative integer.
Obviously, the difference is only positive if the number being subtracted is smaller than the number it is being subtracted from.
None of the x-values are repeating so it's C (I did this last year in algebra 2)
Answer:
Step-by-step explanation:
You can use the foil technique (first outer inner last)
(3x - 1)(-x + 4) = (3x · (-x)) + (3x · 4) + ((-1) · (-x)) + ((-1) · 4)
= 
=
3n + (4n - 2) = 15
is how this equation would be displayed.
Now let's solve for x.
We can distribute a 1 to each term in the parentheses (which doesn't do much) to allow us to combine like terms.
3n + 4n - 2 = 15
Combine like terms.
7n - 2 = 15
Add 2 to both sides.
7n = 17
Divide both sides by 7.
n = 17/7
