Answer: -10
Step-by-step explanation:
9) answer is Hypotenuse
10) opposite
I think that is the answer because it says 2/5 where two rows are shaded and three more rows remain unshaded so, when you add that three and two it's altogether 5, so I think that is the answer, please check out the document I have uploaded.
Not sure if you have an answer choice but with my guess distribute the sums and it should leave an expression of 8X+28
