An example would be:
3x^2 + 6
and

The second way is found by dividing the first one by 3).
Answer:
38°
Step-by-step explanation:
a²=b²+c²-2bc cos A
5²=3²+7²-2(3)(7) cos A
-33 = -42 cos A
A = 
(-33/-42)
A = 38°

Answer:
B
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x + 7)² + (y - 5)² = 16 ← is in standard form
with centre = (- 7, 5 ) and r = 
= 4 → B
