Q square =-1 what is q​

9514 1404 393

  ±i

Step-by-step explanation:

  q² = -1

  q = ±√(-1) = ±i . . . . . . i is the name given to the square root of -1.

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
