Rectangular tennis court has an area of 2840 square feet. if the width of the rectangle is 40 feet, what is the length

length 71

Step-by-step explanation:

area = length x width

2840 = l x 40

divide both sides by 40

length is 71

x-3y=3x

8y=6x8

y=6x

Step-by-step explanation:

Meaning of linear equationA linear equation is a equation that goes at a constant pace and won't change overtime, so functions like x squared and functions that multiply x and y together doesn't go at a constant pace, there not linear equations, but functions like y=mx, M representing any constant, that is a linear equation, therefore    x-3y=3x

8y=6x8

y=6x
