2/X^2=4/X+1 times by both denominators
2(x+1)=4(x^2)
2x+2=4x^2
4x^2-2x-2=0
(2x+1)(2x-2)=0
x=2x+1 or 2x-2
x=-1/2 or 1

Answer:
La anchura será de:
6 cm
Step-by-step explanation:
El formato original corresponde al 100%
Si se reduce un 60% quiere decir que:
100 - 60 = 40%
la reducción queda al 40%
entonces, por regla de tres:
15cm es al 100%
A cm es al 40%
A = 15*40/100
A = 6cm
To find the 7th term, all you have to do is plug it in the equation.
First n would equal 7 because we are looking for the 7th term.
Now, let's plug everything we know into the equation.
a7 = 2+5 * (7-1)
= 2 + 5 * 6
= 2 + 30
= 32
In conclusion, the 7th term would equal 32.
