Find the area of each square given the side S or the perimeter P. S = 2 yd? Please and Thank u!

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

Graph the system: f(x)= 3/x-2; f(x)= 1/2x + 2

Which is the equation of an ellipse with directrices at x = ±4 and foci at (2, 0) and (−2, 0)?
