Answer:
Yes, because the discriminant is negative.
Step-by-step explanation:
when the discriminate is negative it is a negative square root which is not a real number.
The 2 angles given are vertical angles, which mean they are the same.
So we have: 3x +1 = 64
Subtract 1 from each side:
3x = 63
Divide both sides by 3:
X = 63 / 3
X = 21
The answer is A.

Answer:
Add all the values up and divide by 7 ( as there are 7 values in the data set)
Step-by-step explanation:
1.9 + 10 + 11 + 16 + 12 + 12 + 14 = 76.9
If you divide by 7, you will get 10.9857142857.
