Answer:
x=15
Step-by-step explanation:
x+165degrees=180degrees
x=180-165
x=15
Answer:
The correct option is C.
Step-by-step explanation:
The given equation is

It can be rewritten as
.....(1)
The standard form of an ellipse is
....(2)
Where (h,k) is center of the ellipse.
If a>b, then the vertices of the ellipse are
.
From (1) and (2) we get

Since a>b, therefore the vertices of the ellipse are


The vertices of the given ellipse are (10, –7) and (2, –7). Therefore the correct option is C.
Answer:
y = x +3
Step-by-step explanation:
Step-by-step explanation:
26. x²+5x+25/4 = (x + 5/2)²
29. x²/4y²-2/3+4y²/9x² = (x/2y - 2y/3x)²
I’m pretty sure it’s C. because half of 12 is 6 so if they’re buying a pound and a half it would be 12+6, which is 18
