Answer: 17
21-4=17
4+17=21
21+17=38 and so on..
Answer: B. Line AC is congruent to line BD
Step-by-step explanation:
The Hypotenuse-Leg Theorem states that two right triangles are congruent if and only if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of the other right triangle.
Since they both share Leg DC, their hypotenuse should be congruent to use this proof.
Because for input=-2 there are more than one outputs. It means the this is not a function and it’s impossible to find a rule.
Answer:
I think it might be -2....
The second is this I hope it helps
