Answer: ?, C, (6, 5.7, 5.68)
Step-by-step explanation:
I cannot help you with the first question because you didn't give me the whole question.
2) A square and a rhombus are always rectangles.
Note: a rectangle isn't always a square
3) You round up if the number is 5-9 and round down if it's 0-4
a. 5.6 --> 6 so round up to 6
b. 5.67 --> 7 so round up to 5.7
c. 5.678 --> 8 so round up to 5.68
Hope this helped. And brainliest please :D
