Answer:
1) I got 2/e
2) I got 2/3
Explanation:
I uploaded the work I did, hopefully it shows up. I thought that would be more helpful than trying to explain it completely.
For 1, use the quotient rule and simplify.
For 2, use chain rule.
The figure is not marked in any way that would indicate it is a parallelogram. If we assume it is, then
... BE = DE
... 10x -3 = 8x -1 . . substitute the given expressions
... 2x = 2 . . . . . . . . add 3-8x
... x = 1 . . . . . . . . . . divide by 2
The appropriate choice is ...
... A. 1 unit
_____
Since the figure is not marked to indicate BE=DE, you could argue that any answer is correct.
