For this case we must simplify the following expression:

We must add similar terms taking into account that:
- Equal signs are added and the same sign is placed.
- Different signs are subtracted and the major sign is placed.

Thus, the simplified expression is:

Answer:

Answer: radius: 6, center: (3,-4)
Step-by-step explanation:
<span>f(x) = (x – 4)(x + 2),
x-intercept means that f(x) = 0.
0 = (x-4)(x+2)
(x-4)=0, x= 4, point (4,0)
(x+2)=0, x = -2, point (-2,0)
This graph has 2 x-intercepts: (4,0) and (-2,0).
From given answers we can choose only </span>(-2,0).
Answer:
SMA= 24 degrees
Step-by-step explanation:
add the other given angles together: 66 + 90= 156
subtract 158 from 180 (every triangle has a total of 180 degrees): 180-156 = 24
