Which three lengths could be the lengths of the sides of a triangle???? I RLLY NEED HELP!. im not so good with math.. :(

B .7 cm, 25 cm, 11 cm
C. 9 cm, 22 cm, 11 cm
D. 6 cm, 22 cm, 10 cm? (1po

A. In order to be able to form a triangle, two sides must add up to be greater than the third side in all cases.

First things first: a triangle has three sides, and the longest side of the three cannot have a length greater than the sum of the other two sides. The units here are all the same, but in the future, check your units before calculating.
As such,
A. 10 + 14 = 24 > 23
B. 7 + 11 = 18 < 25
C. 9 + 11 = 20 < 22
D. 6 + 10 = 16 < 22
A is the only possible triangle because the sum of its smaller sides is less than the length of the triangle's longest side, thus A is the right answer.
As such,
A. 10 + 14 = 24 > 23
B. 7 + 11 = 18 < 25
C. 9 + 11 = 20 < 22

A is the answer because the middle value which is b must be less than the addition of the first and last values.
