Please try to follow me, as I demonstrate a method of solution. 
This could get complicated.  I'll try to go slowly, and you must
stop me if I do anything that's not clear.

Ready ?

You said that                    -5c/8  =    20

Multiply each side by  8:  -5c     =  160

Divide each side by  5 :   - c      =    32

Multiply each side by -1 :   c      =  -32

3xy-5x+9y-45

Step-by-step explanation:

Step by Step Solution

STEP1:STEP2:Pulling out like terms

 2.1     Pull out like factors :

   3y - 15  =   3 • (y - 5) 

Equation at the end of step2: (x • (3y - 5)) + 9 • (y - 5) STEP3:Equation at the end of step 3 x • (3y - 5) + 9 • (y - 5) STEP4:Trying to factor a multi variable polynomial

 4.1       Split       3xy-5x+9y-45 

 4.1       Split       3xy-5x+9y-45 

             into two 2-term polynomials

             -5x+3xy   and    +9y-45

             This partition did not result in a factorization. We'll try another one:

             3xy-5x   and    +9y-45

             This partition did not result in a factorization. We'll try another one:

             3xy+9y   and    -5x-45

             This partition did not result in a factorization. We'll try another one:

             3xy-45   and    +9y-5x

             This partition did not result in a factorization. We'll try another one:

             -45+3xy   and    +9y-5x

             This partition did not result in a factorization. We'll try

tia_tia [17]

\large \green{ \underline{ \blue{ \boxed{\bf{ \red{Given -}}}}}}

Four points which lie at (0,0) ; (0,2) ; (2,2) ; (2,0)

\large \green{ \underline{ \blue{ \boxed{\bf{ \red{To \: Find-}}}}}}

What is the figure formed?What is the area of the figure?

\large \green{ \underline{ \blue{ \boxed{\bf{ \red{Solution-}}}}}}

The given points lie on graph as per the order given in the attachment.

Which shape?

As the points lie 2 units apart from their adjacent sides. It can be a square or rhombus.

The opposite pairs of sides are also parallel to each other. The adjacent sides of the figure formed are also perpendicular to each other.

<u>Hence! the figure formed is a square.</u>

What is the area?

\large{\sf{ \longmapsto Area_{(square)} = s \times s}}

\large{\sf{ \longmapsto Area_{(square)} = {s}^{2} }}

\large{\sf{ \longmapsto Area_{(square)} = {(2)}^{2} }}

\large{\sf{ \longmapsto Area_{(square)} = 4 \: sq. \: units}}
