Examine rectangle JKLM, shown below.

Mathematics
1 answer:
IRISSAK [1]3 years ago
5 0

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

o-na [289]
1. You have that:
 -The <span>police car accelerates 60 meters per second.
 - The minivan has a speed of 45 meters per second and is 600 meters ahead of the police car at the beginning of the chase.
 2. Therefore, you have:
 V1xt=V2xt-600
 V1 is the speed of the minivan and V2 is the speed of the police car
 3. The time is:
 t=-600/V1-V2
 t=-600/(45-60)
 t=40 seconds</span>
