Answer:

Step-by-step explanation:

12  .x=3                y= -3

-x+2(y-1)

=-3+2(-3-1) = -3 -6 -2 = -9 -2 = -11

13.a=3

-5(a^2) -a + 5

=-5(3^2) -3 + 5  =  -5(9) +2  = -45 +2 =-43

14.  a = -2             b=4

-4a +3(2b-1)

= -4(-2)  +3( 2(4)-1 ) =8 +3(8-1)  = 8 +3(7) = 8 +21 =29

15. x = -2

3x^2 - 4x +1  =3(-2^2) -4(-2) +1 =  3(4) -4(-2) + 1 = 12 +8 +1 =20 +1 =21
