OMG YES PERUOD DUHDNSJJFJGJ
A * b = 30
a - b = 1
a + b = 11
take ur last 2 equations, and add them
a - b = 1
a + b = 11
--------------add
2a = 12
a = 12/2
a = 6
now its just a matter of subbing
a + b = 11
6 + b = 11
b = 11 - 6
b = 5
so a = 6 and b = 5...whose product is 30, whose difference is 1, and whose sum is 11.
Step 
<u>Find the length of the side MN</u>
we know that
Applying the Pythagorean Theorem

Solve for MN

in this problem

Substitute in the formula above



Step 
<u>Find the value of cos (M)</u>
we know that
in the right triangle MNL


Substitute



therefore
The answer is
The value of cos(M) is equal to 
Hello There!
Area = l x w
14 =

Multiples of 14:
1 and 14
7 and 2
7 and 2 are the only ones with a difference of 5.
Therefore, the length is 7ft and the width is 2ft.
Hope This Helps You!Good Luck :)
