2(3x-0.1)+2x+4 при x= -0.02 решить надо и найти значения выражения.

-6x+0.2+2x+4                                                                                                             -6x+2x+4.2                                                                                                                -4x+4.2    -4*(-0.002)+4.2=0.08+4.2=4.28                                                                                                                         

-2(3x-0.1)+2x+4 при x= -0.02
-2(3x-0.1)+2x+4=-6x+0,2+2x+4=-4x+4,2=-4*(-0,02)+4,2=0,08+4,2=4,28
