HURRY ONLY 5 MINUTES LEFT 100 POINT Which choice shows three lengths that cannot be the lengths of the three sides of a triangle? A 2 cm, 8 cm, 8 cm B 2 cm, 3 cm, 6 cm C 4 cm, 5 cm, 7 cm D 5 cm, 6 cm, 9 cm

I think the answer is a  

Step-by-step explanation:  

A does show the triangle length because both lines on the side has to equal the same but the bottom line is shorter so is 2 cm, 8 cm,. 8 cm.   Hope This Helps!

C

Step-by-step explanation:

A triangle has three sides, three vertices, and three angles. The sum of the three interior angles of a triangle is always 180°. The sum of the length of two sides of a triangle is always greater than the length of the third side.

bottom left

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
