Answer:
6) x=9.75
10) Triangle OMN ~ Triangle ODK; SSS ~
11) SSS ~ theorem
12) SSS ~ theorem
Step-by-step explanation:
For #6, since the polygons are similar, then it must mean AD is congruent to JM and CD is congruent to LM. Now we can set up the proportion 39/20=x/5 and solve. Solving for x gets us x=9.75, so C is the correct choice
For #10, there's no information about angles whatsoever in the diagram, so B and C must be wrong. D must be wrong as well because if the triangles weren't similar, then why is OJ ~ JM and OK ~ KN? So thus, the triangles are similar by SSS.
For #11, this is sort of a no-brainer because there's no mention of angles, so D must be correct.
For #12, same concept, no mention of angles, all sides are similar to their respective sides of the different triangles, so A is correct.
<u>Answer:</u>
<u>Step-by-step explanation:</u>
- Perimeter: 2B + 2L
- => 2(3n - 7) + 2(n + 5)
- => 6n - 14 + 2n + 10
- => 8n - 4
<u>Conclusion:</u>
Therefore, the perimeter in terms of n is 8n - 4.

Answer:
m=(Fr) /v^2
Step-by-step explanation:
Fr=mv^2
(Fr)/v^2=m
Answer:
x = 3/2, -3
Step-by-step explanation:
2x^2 + 5x - 9 = 2x
2x^2 +3x -9 = 0
(2x - 3) (x + 3) = 0
x = 3/2
x = -3
J is the answer it’s a proportion
Divide 32/12 = 2.666
2.6666 x 2 1/4= 5.85
