Answer:
angle 2
Step-by-step explanation:
adds up to 180 degrees
20
This is because
2x+(6x+20)=180
8x+20=180
8x=160
8x/8=160/8
X=20
Replace the 'x' in the formula for g(x) by f(x):-
g(f(x)) = (x-7)^3
Its D
Answer:
C
Step-by-step explanation:
Answer:

Step-by-step explanation:
The equation of a circle:

(h, k) - center
r - radius
We have the center (4, -3) and the point on the circle (9, -3).
The length of radius is equal to the distance between a center and an any point on a circle.
The formula of a distance between two points:

Susbtitute:

The center (4, -3) → h = 4, k = -3.
Finally we have:
