Answer:
3 1/5 (or 3.5)
Step-by-step explanation:
2(7) - 7(-1)
_______
7 + -1
Next:
14 + 7 (two negatives make a positive)
_____
6
Next:
21/6 which equals 3 1/2 (3.5)
Answer: each number represents the sum of the two numbers
Step-by-step explanation:
I’ve never done this question before but bright to sum of the numbers together
Answer:
(C) 2√15
Step-by-step explanation:
Recognize that all the triangles are right triangles, so are similar to each other. In these similar triangles, the ratio of the short side to the long side is the same for all.
... CB/CA = CT/CB
... CB² = CA·CT = 10·6 = 60 . . . . . . . . . . multiply by CA·CB; substitute values
... CB = √60 = 2√15 . . . . . . . take the square root; simplify

<em>Comment on this solution</em>
The altitude to the hypotenuse of a right triangle (CB in this case) divides the hypotenuse into lengths such that the altitude is their geometric mean. That is ...
... CB = √(AC·CT) . . . . as above
This is true for any right triangle — another fact of geometry to put in your list of geometry facts.
