Find c
The question is incomplete. However, I'll assume the expression is a perfect square.
To find c, we make use of the following formula
Where
By comparison with
So, becomes

Answer:
Step-by-step explanation:
Factoring x2-6x-30
The first term is, x2 its coefficient is 1 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is -30
Step-1 : Multiply the coefficient of the first term by the constant 1 • -30 = -30
Step-2 : Find two factors of -30 whose sum equals the coefficient of the middle term, which is -6 .
-30 + 1 = -29
-15 + 2 = -13
-10 + 3 = -7
-6 + 5 = -1
-5 + 6 = 1
-3 + 10 = 7
-2 + 15 = 13
-1 + 30 = 29
Answer:
median
Step-by-step explanation:
the median would make the score as good as possible, because there could be possible outliers. this really depends on if there are outliers or not. here is an example of what i need:
say you are trying to show your parents your grades:
here are your scores:
38, 88, 90, 91, 93, 95, 100
the median would be 91, which looks better.
the mean would be 85.
even though a <em>majority</em> of your grades are good, the one 38 makes the average go down. therefore, the median is a better advertiser.
