Answer:
14/18 = 0.778
Step-by-step explanation:
14 divided by 2 = 7
18 divided by 2 = 9
7/9 is the same as 7 divided by 9
= 0.778
(4x² + 6) + (2x² + 6x + 3) = 4x² + 6 + 2x² + 6x + 3 = 6x² + 6x + 9

Answer:
- 9, - 5, - 1
Step-by-step explanation:
Calculate the mean of 3 and - 13, that is
= = - 5
That is
- 13, - 5, 3
Now find the mean of - 13 and - 5, and - 5 and 3
= = - 9
= = - 1
Thus
- 13, - 9, - 5, - 1, 3

Answer: B )
D) x=90, y=43
This is because sides AB and AC are equal so angles B and C are thus both 47.
Also, since both angles BAD and BAC are equal, and x is likely 90, that must be 180-(90+47)=43.
