Cho hàm f(x) thỏa f(2)=5 và f′(x)=2x[f(x)]2 với mọi x∈R. Tính f(3).

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

d.) 48 units

step-by-step explanation:

well

44-3-3-3=35

35+4+4+4+4=51

so the ansewr would be 51 degreesat 7: 00
