The general solution of <span>y' + 2xy = (x^3) is y(x) = c1e^(-x^2)
The general solution of </span><span>ydx = (y(e^y) - 2x)dy is x = c1/(y(x))^2 + (e^y(x) ((y(x))^2 - 2y(x) + 2)/(y(x))^2
</span>
The general solution of<span> (dP)/(dt) + 2tP = P + 4t - 2 is P(t) = c1e^(t - t^2) + 2</span>
Answer: 
Step-by-step explanation:
Given:

To make
the subject of the formula means that we want to make
to stand alone , the first thing to do is to multiply through by 1/4a , that is

take the square of both sides:

Answer:
x=20
Step-by-step explanation:
The line is a straight line, which is 180 degrees
x+100+3x = 180
Combine like terms
100+4x = 180
Subtract 100 from each side
100+4x-100=180-100
4x=80
Divide by 4
4x/4 = 80/4
x=20
