88 cards. 
(X +7)/2 = 44 Multiply each side by 2X+7 = 88 Subtract 7 from both sidesX = 81

He started with 81 cards and added 7 then his dog ate half of that which is 44. 
So your answer is 88. He started with 88.

Which of the following is not performed when solving r^2+12r-6=0 by
PtichkaEL [24]

Answer:

B.)  why Factor p+ 12r - 6,  I did not do that below.

Step-by-step explanation:

r^2+12r-6=0

solve:

r^2  +  12 r  +   36  - 36  - 6  = 0

factor the trinomial by completing the square.

( r + 6)^2  -42 = 0

(r + 6)^2  = 42

r + 6  =  root(42 )  or  r + 6 = - root(42)

r = -6 + root(42)  or  r = -6 -root(42)
