Step-by-step explanation:

2x + 2(3x - 1) = 3(x + 1) \\ 2x + 6x - 2 = 3x + 3 \\ 8x - 2 = 3x + 3 \\ 8x - 3x = 3 + 2 \\ 5x = 5 \\ x = 1inch

perimeter \: of \: rectangle \\ 2x + 2(3x - 1) \\  = 2(1) + 2(3(1) - 1) \\  = 2 + 2(2) \\  = 6 \: inches

perimeter \: of \: \: triangle \\ 3(x + 1) \\  = 3(1 + 1) \\  = 3(2) \\  = 6 \: inches

I need help for #1 (an explanation would be great too).
Ivan

Answer:

±6i√2

Step-by-step explanation:

Recall that the square root of a negative number is imaginary, which is shown by the use of "i."

Examples:  √4 = ±2; √4 = i√4 = ±i2

Then √72 = ±√36√2 = ±6√2, and

   

      √(-72) = ± i√36√2 = ±6i√2

         

Note that this is identical to the result shown in the problem:  √(36·2·(-1) )
