Can anyone help??? due in 10 mins please.
belka [17]

Step-by-step explanation:

(6x+4)+(4x+26)+110°=180°{straight angle}

10x+140=180°

10x=180-140

x=40/4

x=10

(6x+4)=(6×10+4)=(60+4)=64°

(4x+26)=(4×10+26)=40+26=66°

hope it helps.

how that every member of the family of functions y = (4 ln(x) + C)/x is a solution of the differential equation x2y' + xy = 4. (
Sergeeva-Olga [200]

y=\dfrac{4\ln x+C}x\implies y'=\dfrac{x(4\ln x+C)'-(4\ln x+C)(x)'}{x^2}=\dfrac{4-4\ln x-C}{x^2}

Substitute this into the differential equation:

x^2y'+xy=4-4\ln x-C+4\ln x+C=4

so every solution of the given form y is a solution.
