Answer:

so first do 3(x+6) so multiply 3*x and 3*6

then you get 7x+3x+18=8

the add all like terms 7x+3x

then you get 10x+18=8

now subtract 18 from both sides to get x by its self 10x+18-18=8-18

then you get 10x=-10

no divide each side by 10x

then you get x=-1

Find a general solution of y" + 4y = 0.

klio [65]

Answer:

$y(x)=C_{1}cos2x+C_{2}sin(2x)$

Step-by-step explanation:

It is a linear homogeneous differential equation with constant coefficients:

y" + 4y = 0

Its characteristic equation:

r^2+4=0

r1=2i

r2=-2i

We use these roots in order to find the general solution:

$y(x)=C_{1}cos2x+C_{2}sin(2x)$

Cada dimensión será de 8,75 porque si la longitud es de 25 m de largo y el ancho es 10, si los sumamos y obtendremos 35. Así que 35 dividido entre 4 es 8,75
