given the side lengths of 6, 13, and 20, determine whether the triangle is acute , right , obtuse, or not a triangle.

Not a triangle.

Step-by-step explanation:

Sum of the two smaller sides must be greater than the largest side.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
