MN and KL are parallel. If JM = 6, MK = 12, and LN = 18, what is NJ?
2 answers:
Answer:
Step-by-step explanation:
We have been given that MN and KL are parallel. If JM = 6, MK = 12, and LN = 18. We are asked to find the measure of NJ.
Since line MN is parallel to KL, so triangle JMN is similar to JKL.
We know that corresponding sides of similar triangle are proportional. We will use proportion to solve for NJ as:
Multiplying both sides by 18, we will get:
Therefore, measure of NJ is 9 units.

Answer:
Option C, 14/21=9/21 is the proportion.
Step-by-step explanation:
Given:
a.5/7 = 10/12
b.9/15 = 12/18
c.4/6 = 8/12
d.14/21 = 9/12
We have to find the proportions.
In proportion two ratios are equal, as it has an equality sign in between so both side must be of same ratio in its simplest form.
Let's work with option C
⇒
To find the simplest form we have to divide the numerator and denominator with same digit (or its factor).
Simplest form of =
,
=
Simplest form of =
Both sides in option C have equal ratios of 2/3.
So 4/6=8/12 is in proportion.
Answer:
3120
Step-by-step explanation:
step 1:multiply 8 with 0 and 7 with 0
step 2:add a 0 in the end and multiply 8 with 4 . you get 32. take 2 and carry over 3. multiply 7 with 4. you get 28 . add 3 you get 31. now add. you get 3120
