You're given two side lengths of 6 cm and 9 cm which measurement can you use for the length of the third side to construct a valid triangle

The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side. (Hence, the sum of the two smaller sides is greater than the larger side)

This means that the third side is shorter than 6 and 9 combined, but also 9 is shorter than 6 and the third side combined.

If the third side's length is x, then 3<x<15.

good luck!

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
