All of the following expressions are equivalent to 12w + 6, except: -1(12w - 6)
(3 + 6w)2
6(1 + 2w)
-1(-12w - 6)

-1(-12w - 6)

Step-by-step explanation:

trust me ;)

Number 1 is your answer

-1(12w-6)

Step-by-step explanation:

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
