Answer: 49

Step-by-step explanation:

The missing constant term in the perfect square is 49.

x^2 + 14x + 49

We need a squart root of something to make the factor add up equal to 14x. If it's a perfect square, we could divide 14 by 2, 14/2 = 7, and we multiply 7^2, we get 49, which is a perfect square.

I really don't understand this
RoseWind [281]

Answer:

-1

Step-by-step explanation:

The mean is the sum of all values divided by the amount of values.

We take the sum of all the numbers:

-3 + -8 + 12 + -15 + 9

-11 + 12 + -15 + 9

1 + -15 + 9

10 + -15

-5

We then divide the sum by how many number we have (we are given 5 numbers):

-5/5 = -1

Therefore, our mean is equal to -1.
