Carmen simplifies the expression (4 y + 8 x + 6) + 25 + (4 x + 6 y + 7). The coefficient of the variable y in her simplified answer is

10

Step-by-step explanation:

(4y + 8x + 6) + 23 + (4x + 6y + 7)

10y + 12x +23 + 7 + 6

10y + 12x + 38

y = 10

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

step-by-step explanation:

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
