Hey there! :)
The first arrow is on 2. That means the expression starts with 2.
You can cross out the last choice
The second arrow is on -1. That means the answer is -1
The correct choice is C.
Hope this helps :)
Answer: -49
Step-by-step explanation: I just kept subtracting by two and changing the first number because the last digit alternates between 1, 3, 5, 7, and 9.
48 ten units and 1 five unit.
Unfortunately your response would only be true if CD was perpendicular to AB. However we don't know if CD is perpendicular or not. So we don't have enough information. The actual answer is choice E) None of these.
