Answer:
x = 16
Step-by-step explanation:
(5x + 12)° + (6x - 8)° = 180°
(5x + 12 + 6x - 8)° = 180°
(11x + 4)° = 180°
11x + 4 = 180
11x = 180- 4
11x = 176
x = 176/11
x = 16
1) Final expression: 
2) Final expression: 
Step-by-step explanation:
1)
The first expression is

First, we remove the 2nd bracket by changing the sign of all the terms inside:

Now we group the terms with same degree together:

Now we solve the expression in each brackets:

So, this is the final expression.
2)
The second expression is

We apply the distributive property, so we rewrite the expression as follows:

Solving both brackets,

Now we group terms of same degree together:

And solving each bracket,

So, this is the final expression.

because there variables represent 1 so 1 cant be bigger than one and the other two have real equations
Answer:
La afirmación es falsa, no todos los divisores de 100 son divisores de 50, ya que solo se toman en cuenta sus divisores comunes, los cuales son todos los divisores de 50. Expresamos a 100 en sus factores primos: 100 = 2 · 2 · 5 · 5 = 2² · 5² Divisores de 100: {1, 2, 4, 5, 10, 20, 25, 50, 100}
