Answer:

28/3

Step-by-step explanation:

We see that the triangles are simalar to eachother, so we can set up this ratio:

x/(8+x) = 7/13

x = 56/13 + 7x/13

13x = 56 + 7x

6x = 56

x=56/6=28/3

Answer:

x = 0 , 3

Step-by-step explanation:

$\frac{1}{x}=\frac{x+3}{2x^{2}}\\\\1*2x^{2}=x*(x+3)\\\\2x^{2}=x*x+x*3\\\\2x^{2}=x^{2}+3x\\\\2x^{2}-x^{2}-3x = 0\\\\x^{2}-3x =0\\\\x(x-3)=0$

x = 0 ; x - 3 = 0

x = 0 ; x = 3

SOLUTION:

GCF = 2

= 6y^3 + 10n^2

= 2 ( 3y^3 + 5n^2 )
