The triangle inequality applies.
In order for ACD to be a triangle, the length of AC must lie between CD-DA=0 and CD+DA=8.
In order for ABD to be a triangle, the length of AC must lie between BC-AB=3 and BC+AB=9.
The values common to both these restrictions are numbers between 3 and 8. Assuming we don't want the diagonal to be coincident with any sides, its integer length will be one of ...

Answer: 8n-5
Step-by-step explanation:
Answer: 87 m
Step-by-step explanation:
This problem can be solved by using a simple ratio and proportion.
The way you figure this out is::
Model = 12 m/ 1 cm = x/7.25 cm
Solve for x and you should receive this answer:
x = 87 m
hope I helped, best wishes to your future studies...
-a
My answer is a and c becuase they equal the same on each side
Standard form is just putting (in this case) variables in alphabetical order. First we simplify- 2x+4=4y would become 1/2x+1=y. This is already in standard form, as numbers w/o variables come at the end. simplifying the next one is more tricky. first you get a variable/number alone-
9-2x-2y=4x+3
9-2y=6x+3
6-2y=6x
1-1/3y=x
1=x+1/3y
3=x+y
x+y=3
sorry if I was wrong and not of any help, But I do believe this is correct.
