Answer:
65x
Step-by-step explanation:
Observe que estos son terminos similares... por lo que podemos simplemente sumarlos y restarlos. Entonces obtenemos:
25x + 12x + 31x - 8x + 5x
= 37x + 31x - 8x + 5x
= 68x - 8x + 5x
= 60x + 5x
= 65x
<span>A rational number can be written in the form:
</span>

<span>
The number

isn't equal to zero because the division by zero is not defined. So we can represent rational numbers by a repeating or terminating decimal, for instance in the following four exercises we have:

Base = x
height = x-4
Area = .5 * height * base
48 = .5 * (x-4) * x
96 = x^2 -4x
x^2 -4x -96=0
x = 12
base = 12
height = 8
Step-by-step explanation:
8x+3x-15-5x+20
6x+5
I think correct answer is 6x+5
