Answer:

Step-by-step explanation:
Given that

Here


We know that
M dx + N dy=0 will be exact if

So


it means that this is a exact equation.

Noe by integrating above equation

Given that
x= 0 then y= 1

C=4
So the our final equation will be

Answer:i think its 183
Step-by-step explanation
1560 devided by 85= 18.3 but just take away the decimal
Answer:
First side is: 12cm
Second side is: 36cm
Third side is: 16cm
Step-by-step explanation:
Let x represent the shorter side
Then 3x represents the second side, and
x + 4 represents the third side.
Perimeter of three sides:
P = x + 3x + (x + 4)
Perimeter is 64, so
64 = x + 3x + (x + 4)
64 = 5x + 4
60 = 5x
12 = x
First side is x: 12cm
Second side is 3x: 3(12) = 36cm
Third side is x + 4: 12 + 4 = 16cm
Answer:

Step-by-step explanation:
Notice that buy construction of a parallelogram,the angles
and
must equal each other. Then, based on the info given, we can write the following equation:

Then, angle
=
which is also equal to angle B
and since the addition of all internal angles of the parallelogram must equal
, then:

and therefore, since
and
must be equal, then:
