Please help me out on this one

Try this triangle: 3ft, 4ft, and 1 ft

Is the first plus second greater than the third? Is 3+4> 1?
Is the second plus third greater than the first ? is 4+1 >3?
Is the third plus first greater than the second? Is 3+1 >4
Can it make a triangle? Explain why?

No

Step-by-step explanation:

The sum of the lengths of any two sides must be greater than the third side.

3+4>1

4+1>3

3+1<4

Because sides 3+1 is not greater than 4, it means it can't  be a triangle.

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.

yes yes yes yes yes yes yes yes yes
