The sum of two numbers is equal to 11 and the difference is 19. What are the two numbers?

How do i put 3(x+7) in distributive property

Let f(x) = 5/x and g(x)=2x2+5x. what two numbers are not in the domain of f o g

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.
