Answer:
Step-by-step explanation:
If you want to factor
, you could throw that into the quadratic formula with a = 1, b = 11 and c = 0, but the easier thing to do is to factor out what's common in those 2 terms. m is common, so when we factor it out:

That's the factored form.
By the Zero Product Property, either
m = 0 or m + 11 = 0.
So the 2 solutions to this are
m = 0 or m = -11
Not sure how far you need to go with this.
Zeros are:



Looks like only

and

are offered as answers, though.
The greatest common factor of 14 and 28 is 14
If it costs 3n+5, you have to plug 7 in for n and solve. 3(7)+5=26 so $26
