Will give abrainlest and 50pts which solution to the equation 3/a+2 + 2/a = 4a-4/a^2-4 is extraneous? a= -2 a= -2 and a= 4 neither a= -2 and a= 4 a= 4

a=-2 is extraneous solution.

Step-by-step explanation:

Given the equation

we have to find the extraneous solution.

An extraneous solution is a solution to an equation, that emerges from the process of solving the problem but is not a valid solution to the problem.

On solving, we get

The solution is a=4 and a=-2

Here the solution a=-2 is the valid solution as it makes the denominator 0.

⇒ a=-2 is extraneous solution.

Option 1 is correct.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

the answer is y = 11.54

hope this : )
