Which inequality can be used to explain why these three segments cannot be used to construct a triangle? ac + ab > cb ac + cb < ab ac + cb > ab ac + ab < cb

we know that

The sum of the lengths of any two sides of a triangle is greater than the length of the third side (Triangle Inequality Theorem)

Based on this theorem, to be able to construct a triangle with three segments AB, BC and AC, the following inequalities must be fulfilled

1)

2)

3)

With only one that is not fulfilled, the triangle can not be made

So

Analyze the options

option a) -----> is fulfilling the Triangle Inequality Theorem

option b) -----> is not fulfilling the Triangle Inequality Theorem

option c) -----> is fulfilling the Triangle Inequality Theorem

option d) -----> is not fulfilling the Triangle Inequality Theorem

therefore

the answer is

answer: a

step-by-step explanation:

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
