14x+6=2(5+7x)
14x+6=10+14x
14x-14x=10-16
x= -6
Answer:
Step-by-step explanation:
eq. of any line through (1,2) with slope m is
y-2=m(x-1)
if the line is parallel to x-axis then y=2
if the line is parallel to y-axis then x=1
This system can be a bit tricky unless you write it out:
(2n + 2)(2n - 2) ~ First you have to take one variable and multiply it to each of the other two variables, like:
2n * 2n ~ And:
2n * -2 ~ This gives you:
4n^2 - 4n
Now we do this with the other:
2 * 2n
2 * -2
4n - 4
Now we combine them both while adding like terms:
4n^2 - 4
Therefore your answer is: A. 4n^2 - 4
(This is due to how when having the positive 4n subtracted by the negative it cancels it out. Leaving us with the remaining two terms left.)
I hope this helps, have a great rest of your day! ^ ^
