Identify the independent and dependent variables. The equation A=25w represents the area A (in square feet) of a rectangular dance floor with a width of w feet.

‘A’ would be the dependent variable
‘w’ would be the independent variable

say, y = x+3, then they value y can have depends on what the value of x is. another way to put it is the dependent variable is the output value and the independent variable is the input value. so for y = x+3, when you input x =2, the output is y = 5.

You need to divide 210 square inches by 35 inches and that’s going to give you 6 inches and that’s the length of the hypothenuse of the right triangle i hope that this you : )
