Answer:

B and C both are equivalent to the expression

Answer:

B, C

Step-by-step explanation:

2(8y+1/2) would be equal to 2x8y+2x1/2=16y+1.

2(8y+1/2) would also be equal to 8y+1/2+8y+1/2 because multiplying by 2 is basically just adding the thing you are multiplying to itself.

Answer:

B. (x - 3²)(y-6)

Step-by-step explanation:

Find the expression with a value of 30;

 when x  = -1 and y = 3:

   A.  (x - 3²).y-6

           (-1 - 9).3-6 = -10 x 3 -6  = -30 - 6 = -36

 B.  (x - 3²)(y-6)

          ( -1 -3²)(3 - 6) = (-1 -9)(-3) = 30

C.  x - 3² . (y-6) = -1 - 9.(3-6)

                         = -1-9.-3

                         = -1 - 9 x -3

                         = -1 + 27

                         = 26

D. x - 3².y-6 = -1 - 9. 3 - 6

                   = -1 - 27 - 6

                   = -34
