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.
Answer:
<h2>J = 3</h2>
Step-by-step explanation:
got the answer, attached is drawn
Each Interior Angle = 180° - (360 / sides)
144 = 180 - (360 / sides)
(360 / sides) = 36
sides = 360 / 36
sides = 10
It is a decagon.

Answer:
p = k(d)/u^2
Step-by-step explanation:
<em>BRAINLIEST, PLEASE!</em>
so what you have to do is multiply 3 and 2 and 3 and -14 which ends up being 6x-42x=, then do 15 times -9 and you then do 15 times -5 and that becomes -135x - (-7) then you show it like this= 6x-42x=135x-(-7) the solution would be 36x=-135 divide 36 each side and you get x= 2.28
