Answer:
7. C. 6
8. H. √34
9. A. (1, 3.5)
10. J. 10
Step-by-step explanation:
7. AB = 2y, BC = 6y, AC = 48
AB + BC = AC (segment addition theorem)
Substitute the above values into the equation
2y + 6y = 48
Solve for y
8y = 48
Divide both sides by 8
8y/8 = 48/8
y = 6
8. Distance between P(2, 8) and Q(5, 3):

Let,






9. Midpoint (M) of segment LB, for L(8, 5) and B(-6, 2) is given as:

Let 

Thus:



10. M = -10, N = -20
Distance between M and N, MN = |-20 - (-10)|
= |-20 + 10| = |-10|
MN = 10
Answer: 142 - 75 = 9h
Step-by-step explanation: ok so if 142 is total then subtract 75 from 142 to get 67 if you wanted to know the answer
mark me brainliest if it helped
If we consider it as a combination problem, then we could calculate the how many combinations are there if we pick up three nodes out of six nodes, and then we have:

And the answer should be 20
Answer:its 9
