I'll assume the ODE is

Solve the homogeneous ODE,

The characteristic equation

has roots at
and
. Then the characteristic solution is

For nonhomogeneous ODE (1),

consider the ansatz particular solution

Substituting this into (1) gives

For the nonhomogeneous ODE (2),

take the ansatz

Substitute (2) into the ODE to get

Lastly, for the nonhomogeneous ODE (3)

take the ansatz

and solve for
.

Then the general solution to the ODE is

Each side is 4 sq centimeters long.
Answer
x Is less than 4
Step-by-step explanation:
It will be an open circle and the arrow is going the left direction on the number 4
2x+x+x+68=180
4x=112
x=28
Angle 1: 56 degrees
Angle 2: 28 degrees
Angle 3: 96 degrees
I hope that helps.
The answer is A, it can't land on a number that doesn't exist.
