Simplify the expression 5(x+2x)+(3*5)+(4)(x)

 3x -- 5 x + 9

Step-by-step explanation: = x (3--1) + (--5 + 9)

                                             = x (2) + 4

                                             = 2x + 4

                                  putting x =3

                                           = 2 (3) + 4

                                           = 6 + 4

                                           = 10

step-by-step explanation:

use that smart brain

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
