3x + 1/4 y^2 What is the value of the expression above when x = 3and y = 4? You must shoe all work and calculations to receive full credit.

Respuesta :

Your 3x + 1/4 y^2 would be clearer if written as   3x + (1/4) y^2.

Substituting 3 for x and 4 for y, we get 3(3) + (1/4)(4)^2, or 
                                                               9    +   4  =   13
