Let a=x^2+4. use a to find the solutions for the following equation: (x^2+4)^2+32=12x^2+48. which one of the following are solutions for x? select any/all that apply. -8, -2, 4, 0, 2, -4, 8

-2,0,2

Step-by-step explanation:

The given equation is:

⇒

Substituting in the above equation, we get

⇒

⇒

⇒

⇒

⇒

⇒

Now,  , then substituting the value of a in this equation,

and

⇒

⇒ and

⇒

⇒

Thus, the value of x are -2,0 and 2.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
