Determine if the side lengths 9,9,and 17 form a triangle. If if its a triangle, classify it by its sides

Yes it is a triangle and is an isosceles one as well.

Step-by-step explanation:

Let's try it out by using the Triangle Equality Theorem!

a+b > c, a+c > b, and b+c > a

a = 9

b = 9

c = 17

18 > 17 YES

9 + 17 > 9 YES

9 + 17 > 9 YES

It all checks out!

Since two sides are equal in length, it is an isosceles triangle.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
