ARE THOSE RIGHT LOOK AT THE PICTURES WHATS THE UNKNOWN VALUE

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

60 2(x + 2) in the diagram, gef and hef are congruent. what is the value of x?

Is there a direction u in which the rate of change of f(x,y)equals=x squared minus 3 xy plus 4 y squaredx2−3xy+4y2 at p(1,2) equals 14? give reasons for your answer. choose the correct answer below. a. no. the given rate of change is smaller than the minimum rate of change. b. no. the given rate of change is larger than the maximum rate of change. c. yes. the given rate of change is larger than the minimum rate of change and smaller than the maximum rate of change.
