How can i describe a function with using a equation?

The width of a rectangle is 20 units. can the perimeter p of the rectangle be 64 units when its length x is 11 units? no, because p = 2x + 2(20) no, because p ≠ 2x + 2(20) yes, because p ≠ 2x + 2(20) yes, because p = 2x + 2(20)

Ade and abc are similar. which best explains why the slope of the line between points a and d is the same as the slope between points a and b?

Select the point that is a solution to the system of inequalities. y< =-x+3 y=x^(2)-3x
