Can you check these for me please? Thank you!

Let A = {circle, square} and let B = {3, 4, 5}. Find A X B.

{circle, square, 3, 4, 5}

{ }

{3, 4, 5}

{(circle, 3), (circle, 4), (circle, 5), (square, 3), (square, 4), (square, 5)}

I chose D.

Evaluate: 16 - 10 ÷ 2 + 3

6

8

14

0

I chose C but I think it might also be B.

Which of the following is the slope between the two points (1, 5) and (6, 4)?

1/5

-1/5

5

-5

I chose B
