The answer is D
Step-by-step explanation:
No.
The perimeter is the distance all the way around the triangle.
So it's the sum of the lengths of the three sides.
The sum of three numbers doesn't depend on what order you
add them ... I think that's the 'commutative' property of addition.
So it doesn't matter which side you start with, or even what order
the sides are arranged in. The perimeter is always the same.
Answer: The length of LK is 40.
Step-by-step explanation:
LK = 6x+10
KM = 2x+8
LM = 58
so
LM = LK + KM
or, 58 = 6x+10+2x+8
or, 58 = 8x + 18
or, 58-18 = 8x
or, 8x = 40
so, x = 5
now
LK = 6x + 10
= 6*5+10
= 30 +10
= 40
