Answer:
I believe that the answer is 0
Step-by-step explanation:
All you have to do is add f and g and substitute -2 for x. When you substitute -2, simplify.
Answer:
A) 50°, 65°, 65°
B) 45°, 50°, 85°
C) 20°, 60°, 100°
Step-by-step explanation:
To see if the angles can be used to construct triangles, you have to check if the degrees add up to 180 (Since the degrees in a triangle always have to add up to 180 degrees).
<u>A) 50° + 65° + 65° = 180° (Good!)</u>
<u>B) 45° + 50° + 85° = 180° (Good!)</u>
<u>C) 20° + 60° + 100° = 180° (Good!)</u>
<em>D) 30° + 60° + 70° = 160° (Bad!)</em>
<em>E) 20° + 45° + 120° = 185° (Bad!)</em>
I think the answer is f(2)=6 , but I'm not too sure. Hope this helped somehow!
Answer:
n = 0
Step-by-step explanation:
Multiply parenthesis by 3 and get:
1.) 18 + 9n = 5n + 18 + 3n
Then cancel the equal terms:
9n = 5n + 3n
Collect like terms:
9n = 8n
Move variable to the left:
9n - 8n = 0
n + 0
Plugin the value of 0 into x:
3 (6 + 3 x 0) = 18
5 x 0 + 3 x 0 + 18 = 18
*If the plugged in value have the same result than the answer is correct because 18 + 18.
