The answer of the question is x.
Answer:
225
Step-by-step explanation:
I took the quiz I got this question wrong but the answer is 225
There is no outliers though 102 and 9 are the furthest numbers from the rest, but not a significant outlier
Add the five to each side.
then square it to get rid of the square root
2x+13=(5+x)^2
2x+13=x^2+10x+25
2x=x^2+10x+12
x^2+8x+12=0
(x+6)(x+2)
x+6=0
x+2=0
answers are -2 and -6, however, when pluging -6 in it doesnt work, so it is only -2.
It would be 3 times the sum of x and seven plus 10. This is because first you would would add 7+x (7x) and multiply it by 3. And then add on 10.
