Need asap! follow the process of completing the square to solve x2 = -4x + 3. which of the following equations is used in this process? (2x + 4^)2 = 12 (2x + 4)^2 = 19 (2x + 4)^2 = 28

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.

solving with completing the square

dont think so

step-by-step explanation:

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
