Arectangle has a length that is 4 units longer than the width. if the width is increased by 7 units and the length increased by 5 units, write and equivalent expression for the area of the rectangle

The expression for Area of rectangle is .

Step-by-step explanation:

Given:

A rectangle has a length that is 4 units longer than the width.

Let the width of the rectangle be 'x' Units.

Length of rectangle will be =

If the width is increased by 7 units.

New Width of the rectangle =

Also the length increased by 5 units,

New Length of rectangle will be =

We need to write an equivalent expression for area of the rectangle.

Area of rectangle is given by length times width.

framing in expression form we get;

Area of rectangle =

On Solving the equation we get;

Area of rectangle =

Hence the expression for Area of rectangle is .

step-by-step explanation: g=6

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
