The length of each side of an in quadro triangle is increased by 5 in the perimeter is now 60 in write and solve an equation to determine the original length of each side of the equilateral triangle

I've never been good at math he told he loves but he keeps cheating on me, so it ain't adding up sis

Figure abcd is a parallelogram. if point c lies on the line x = 2, what is the y-value of point c?

To find the extreme values of a function f(x.y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x,y)=xy
