Two sides of a rectangle are 4cm in length. the other two sides are 6cm in length. what is the perimeter of the rectangle? include the abbreviation for millimeter as the units.

200 mm

Step-by-step explanation:

The perimeter of rectangle is given by :-

, where l is length and w is width of the rectangle.

Given : Two sides of a rectangle are 4 cm in length. The other two sides are 6 cm in length.

The perimeter of the rectangle will be :_

We know that 1 cm = 10 mm

Therefore,  perimeter of the rectangle =

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
