Answer:
c
Step-by-step explanation:
Hello Alondra,
To solve this problem, you have to write a proportion using the ratios formed by the similar triangles.
Or proportion can be:
x/(x+2) = 10/15
Cross multiply to solve it:
10x + 20 = 15x
20 = 5x
4 = x
The value of x is 4.
I hope this helps,

Answer:
(x+1)^2+(y-7)^2=8
Step-by-step explanation:
You should try the next one and I can check work or tell you if it is right.
The diameter length can be found be computing the distance that (-3,5) is to (1,9) which is sqrt(4^2+4^2)=sqrt(32).
The radius is half the diameter so it is sqrt(32)/2.
The center of the circle is the midpoint of a diameter. So compute the (Average of x, average of y)=(-1,7)
So plug into (x-h)^2+(y-k)^2=r^2 we get
(x+1)^2+(y-7)^2=32/4
simplifying gives
(x+1)^2+(y-7)^2=8

Answer:
32
Step-by-step explanation:
Add up all the numbers and then divide by how many numbers there are.
The third one down
Because the best line of fit is a line that goes between the plotted points and it HAS to be a straight line and most of the points close to the line
