Answer:
12
Step-by-step explanation:
Since M is a midpoint of LN, we can see 3x equal to x+8. Remove 1 x to get 2x=8. Solve for x to get x=4. <em>Note that this is not the end to your problem. They asked for the length of MN, not the value of x.</em><em> </em>Plugging x into MN give you 4+8, which is 12.
(If you need to show work, here it is)
3x=x+8
2x=8
x=4
MN=x+8
MN=4+8
MN=12

Answer:
x= 17cm
Step-by-step explanation:
given:
sides of a triangle:
x, x-5, 3x
perimeter= 80cm
perimeter of a triangle= side + side + side
80 = x + (x-5) + (3x)
80 = x + x + 3x -5 ------------->(rearranging the like terms together)
80 = 5x - 5
80+5 = 5x
85 = 5x
85/5 = x
17cm = x
