Answer:
x - 6
Step-by-step explanation:
I'm showing you how I solved it in the picture that I have included.
<span>In order to find the standard deviation, we first have to calculate the mean (average) of the numbers. To get this we add all the numbers together and then divide by 12 since there are 12 numbers. The mean = 782. Next, we take each number and subtract the mean, taking the result and squaring it. For this we get: 6724, 2209, 10404, 11664, 729, 1764, 12544, 9, 529, 71824, 1444, 1024. Now we sum all of these up and take the average by dividing the sum by 12. Doing this we get 120868/12=10072. The last step is the take the square root of that number to get the standard deviation. The final result is 100.</span>

If one zeros is x= -7 then the other zero is x=5
Step-by-step explanation:
We are given the function: 
If one zeros of the function is x=-7 we need to find other zero of the function.
We can find zeros of the quadratic equation by factorizing the equation

Factorizing the quadratic equation:

So, if one zeros is x= -7 then the other zero is x=5
