Help please!! Which of the following triplets are possible lengths of line segments that could form a triangle with its vertices at their endpoints? Select the two correct answers

A. 5, 5, and 5

B. 7, 7, and 4

C. 6, 6, and 12

D. 8, 1, and 3

E. 3, 4, and 8

A and B

Step-by-step explanation:

A triangle is a triangle if the sidelengths, a, b, c, in increasing order, satisfy the condition that a+b > c

only A and B satisfy that condition

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
