Answer:
4x - 8 + 4y
Step-by-step explanation:
Given
4(x - 2 + y) ← multiply each term in the parenthesis by 4 ( distributive law )
= 4x - 8 + 4y
<em><u>Perimeter=L+W×2
50+30×2=160.
</u></em>
Answer:
Angle K is congruent to itself, due to the reflexive property
Step-by-step explanation:
Given: ΔLKM is similar to ΔNOM
To find: statement that is not used to prove that ΔLKM is similar to ΔNOM
Solution:
Two figures are said to be congruent if they have same shape and same size.
Two figures are said to be similar if they have same shape but different size.
If two figures are similar then their corresponding angles are equal.
As ΔLKM
ΔNOM,

So, statement that can be used to prove that ΔLKM is similar to ΔNOM is ''Angle K is congruent to itself, due to the reflexive property''
Answer:
Step-by-step explanation:
To find the median, arrange the data in ascending order
10,20,30,40,50,60,70,80,90
Number of data = 9 . It is a odd number
So, median will be the (n+1)/2 th term

Median = 50
Answer:
1
Step-by-step explanation:
6=4+1+n
6 = 5+ n
6-5 = 5-5 +n
1 = n
