Answer:
a. y = -x² + 2x - 8
b. y = 
c. y = x³+ 3
Step-by-step explanation:
6 and 3 is your answer.
6 times 5 is 30
3 times 10 is 30
6+3= 9
One and only one line contains both A and B (assuming, that A and B do not overlap)
Answer:
B
Step-by-step explanation:
We can use the law of cosinse:
=
− 2ab cos(C)
Suppose the two sides are a and b, and the angle betweent them is C.
=
− 2*3*4 cos(60)
We can simplify this to get
=25-12=13
c=
