If f(x)= 2x2-4x and g(x)=5-2x evalute f(x)-g(x) for x=5

For what value of x does 4x = (1/8) x + 5?

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much

The diagonals of a quadrilaretral intersect at (-1,4). one of the sides of the quadrilateral is bounded by (2,7) and (-3,5) determine the coordinates of the other side in order for the quadrilaretral to be a square.
