Answer:
12n+9
Step-by-step explanation:
-Add 10n + 2n (Combine Like Terms)
= 12n
After that, , if there are no other changes to the "9", add it with 12n.
= 12n + 9
Answer: 12n+9
Step-by-step explanation:
Add 10n and 2n.
Combine Like Terms... Like Terms = 10n and 2n.
Leave your 9 alone because there is nothing you can do to it. Add 10n and 2n together to get 12n.
That will give you your answer as 12n+9.
Hope this helps you out! Good luck! ☺

Answer:
Step-by-step explanation:
Distribute 2(x+2):
2(x) + 2(2) = 2x + 2
Use the FOIL method to multiply (2x + 2)(x+6)
(2x + 2)(x+6)
2x(x) = 2
2x(6) = 12x
2(x) = 2x
2(6) = 12
2 + 12x + 2x + 12 = 2 + 14x + 12
Graph the following equation on a graphing calculator, and then you should know how to graph it on paper.
Answer:
x = 45°
Step-by-step explanation:
the sum of the interior angles of a figure = (number of sides - 2) * 180
the sum of the interior angles of this figure = (5 - 2) * 180 = 540°
to find the value of x:
90 + 148+ 2x + 10 + 2x + 112 = 540
2x + 2x = 540 - 90 - 148 - 10 - 112
4x = 180
x = 180/4
x = 45
