Answer:
NM = 8
Step-by-step explanation:
Given rectangle JKLM
JN = x + 3 and JL = 3x + 1
JN = 1/2JL as diagonals bisect each other and N is the midpoint of JL.
Substitute and solve for x:
x + 3 = 1/2(3x + 1)
2x + 6 = 3x + 1
3x - 2x = 6 - 1
x = 5
Find JN
JN = 5 + 3 = 8
Looking at the options, we see that
NM = JN = 8
Correct option is A
Answer: x=9
Step-by-step explanation:
3x+8=35
Subtract 35-8=27
3x=27
27/3=9
x=9
3 inches because a foot is 12 inches and if you cut 12 into 4 pieces you get 3
