Eduardo esta pensando en el numero 16. El numero 16 tiene 5 factores que son, (1, 2, 4, 8, 16)
X=1/2-3y/4
and
x=10/3+2y/3
<span>Simplifying
b4 = 9
Solving
b4 = 9
Solving for variable 'b'.
Move all terms containing b to the left, all other terms to the right.
Simplifying
b4 = 9
Reorder the terms:
-9 + b4 = 9 + -9
Combine like terms: 9 + -9 = 0
-9 + b4 = 0
Factor a difference between two squares.
(3 + b2)(-3 + b2) = 0</span>
Answer: C 20
Explanation: Plug in 2 for k.
2^2 - (2-10) + 4(2) = 20
Well, some integers can be irrational, but not all! :)
