Answer:
C
Step-by-step explanation:
Equation:

1) This sequence of numbers is arithmetic, because each number is the previous one divided by two.
2) the next number in the sequence is 125/2, which is 62.5
Answer:
di you mean m² when you say m2 or not?
15/2 if you are binging it to simplest form
Divide the coefficient of x by 2 then square the quotient.
Add the result to both sides of the equation.





Factor the left-hand side.

Square both sides.

Subtract both sides by 4.


Simplify.


So, x can either equal -4 + 7 or -4 - 7
So, the answer is {-11, 3}
NOTE: You're probably seeing a strange A in the equations. I tried to fix it, but I couldn't. Sorry about that.
