Hello! The answer to your question would be as followed:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    -79-(7*w+3*(4*w-1)=0

 -79 -  (7w +  3 • (4w - 1))  = 0

Pulling out like terms :

  Pull out like factors :

  -19w - 76  =   -19 • (w + 4)

 -19 • (w + 4)  = 0

Equations which are never true :

      Solve :    -19   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

     Solve  :    w+4 = 0

Subtract  4  from both sides of the equation :

                     w = -4

                  w = -4

Hoochie [10]

The New pay in current year is = $ 2225

The old pay in the last year was = $ 2176

percentage (%) increase formula = (new value- old value ) *100 / old value

which becomes,,

\frac{2225-2176}{2176} *100

which equals to 2.3% .

Hence, the average net pay per month increased is  2.3% .

The other options The diagonals bisect each other is not sufficient because in parallelogram diagonals always gets bisected , parallelogram becomes rectangles only if both the diagonals are of same length.

In a parallelogram The opposite angles and opposite sides are always equal.

Hence the correct option is
