Is a triangle with sides of 6 cm, 9 cm, and 16 cm a right triangle? Why or why not?

no

Step-by-step explanation:

The length of any side of a triangle cannot exceed the sum of the lengths of the other two sides. ... Therefore, if two sides have length 6 cm and 9 cm, the third side has length between 9–6 = 3 cm and 9+6 = 15 cm.

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. : )
