Answer:
A. 2,3,4
D 3,4,5
Step-by-step explanation:
In order for segment lengths to be able to form a triangle, the sum of the shortest two must exceed the longest.
A. 2,3,4 . . . 2 + 3 > 4 . . . can make a triangle
B. 2,3,5 . . . 2 + 3 = 5 . . . not a triangle
C. 2,3,6 . . . 2 + 3 < 6 . . . not a triangle
D 3,4,5 . . . 3 + 4 > b . . . can make a (right) triangle
E. 3,4,8 . . . 3 + 4 < 8 . . . not a triangle
Answer:
x(x-7)+4(x-1)/(x-1)(x+1)(x-7)
Step-by-step explanation:
Given the expression x/x²-1 + 4/x²-6x-7
Factorize x²-6x-7
x²-6x-7
= x²-7x+x-7
= x(x-7)+1(x-7)
= (x+1)(x-7)
Replace back into the expression given
x/x²-1 + 4/x²-6x-7
= x/x²-1 + 4/ (x+1)(x-7)
= x/(x+1)(x-1) + 4/(x+1)(x-7)
Find the LCM
= x(x-7)+4(x-1)/(x-1)(x+1)(x-7)
This gives the required expression

Multiples of 5 are A{5,10}
multiples of 2 are B{2,4,6,8,10,12,14}
Multiples of 2 OR 5 are {2,4,5,6,8,10,12,14} for 8 possible outcomes.
Therefore the probability of spinning a multiple of 2 or 5
P(2x or 5x)=8/14 = 4/7
