Answer:

The steps have been shown in the solution below

Step-by-step explanation:

$(3x+1)^{2} - 2(3x+1)=(3x+1)(3x-1)$

$9x^{2} +6x+1 -6x-2= (3x+1) (3x-1)\\\\9x^{2} -1=(3x+1)(3x-1)\\\\(3x+1)(3x-1)=(3x+1)(3x-1)\\$

LHS=RHS Hence, proved.

If (x – 4) + 6 = 2 - (4 - 2x), then x = A. -4 B. -2 C. 2 D. 4

blondinia [14]

Answer:

x=4

Step-by-step explanation:

Remove the parentheses and turn the 4-2x and make it into 4+2x candle the equal term -4 and should be left with x+6=2+2x then move the variable to the left and change the sign so it would be x-2x=2-6 and collect like terms so it would be -x=2-6 and then calculate that and get -x= -4
