Step-by-step explanation:
❃Incase you forgot what the point-slope formula is ☟

❃Incase you also forgot, what the slope formula is ☟

➊ First: We are going to be solving for the slope.

➋Second: Plug in.

The perimeter is all the side lengths added up.
Add up all the side lengths:
6x - 4 + 6x - 4 + 12x + 3 + 12x + 3 + 14x + 13
Add all like terms.
50x + 11
The answer is C) 50x + 11 units
3(n-7)=-30
3n-21= -30
3n = -9
n= -3
Answer:
x=11
Step-by-step explanation:
You do 38/3x+3 and 19/x+7 and then cross mulitply and get 57x+57=38x+266. Then yoy subtract 57 from 266 and get 57x=38x+209. Now you have to subtract 38 from 57 and then answer will be 19. So now you have 19x=209. Finally you divide 209 by 19 and get x=11. Good luck!
