Answer:
see explaination
Step-by-step explanation:
length (l) = 2x+7
width (b) = 9x
area of rectangle = l×b
=(2x+7)(9x)
=18x^2+63x
perimeter of rectangle = 2(l+b)
=2(2x+7)(9x)
=2(18x^2+63x)
=36x^2+126x
Mean=5
Step-by-step explanation:
add the numbers given and divide it by the number of numbers given
Answer:
Step-by-step explanation:
<u><em>To Determine:</em></u>
Solve for x and find angle LMN.
<u><em>Fetching Information and Solution Steps:</em></u>
Considering the angle 
As MO bisects the angle
into two equal angle parts. These equal angles are:


As these angles are equal. i.e.












Hence, 
As
was cut into two equal parts
and 
So,
= 
= 
= 
=
∵ 
=
