Answer:
a= 135
Step-by-step explanation:
18*15=135
<span>(x^5 + 3y)dx - xdy = 0
x^5 + 3y - xdy/dx = 0
3y - xdy/dx = -x^5
dy/dx - 3/x y = x^4
I.F. = e^∫(-3/x) = 1/x^3
(dy/dx)/x^3 - (3/x)y/x^3 = x^4/x^3
(dy/dx)/x^3 - 3/x^4 y = x
(1/x^3 y)' = x
∫</span><span>(1/x^3 y)'dx = xdx
</span><span>1/x^3 y = 1/2 x^2 + c
y = (x^5)/2 + cx^3

B) function A and B have the same x intercept, you can plug in 0 for x to find x intercept and in both function when x = 0, y = 2
