This would be easiest to do by completing the square.
x^2+10x-2=0
x^2+10x=2
x^2+10x+25=27
(x+5)^2=27
x+5=±√27
x=-5±√27
(x+5+√27)(x+5-√27)
To completely factor you must from the Greatest common factor
In this case it is 4z
So the complete factorization is
4z(4x + 5y)
Least common mulitplue is the smallest number that has 49 and 28 as factors
so to do this
find the factor so 49 and 28 and gropu all of them so both are in it
49=7 times 7
28=2 times 2 times 7
therefor yo need at least two 7's and two 2's
that equals
7 times 7 times 2 itme s2=49 times 4=196
answer is 196
M = (8-2)/(4-2) = 3
Therefore the slope is 3 (D).
If you take the original amount 45 and subtract the admission fee 17 you get what is left over which would be 28 dollars. Good Luck and I hope that this helps!!
