8 0

Answer:

2.3lego

Step-by-step explanation:

We can walk through this problem using the cross multiplication method

First 3 1/2 lego is same as 3.5lego

Hence If

Johnny builds 3.5lego in 60min

He can build xlego in 40min

Crosss multiplying we have

Xlego *60= 3.5*40

Xlego= 140/60= 2.3lego

$~~~~\dfrac{d}{dx} \left(\dfrac{3}{1 + \sec x} \right)\\\\\\=3 \dfrac{d}{dx} \left( \dfrac 1{ 1+ \sec x} \right)\\\\\\=3 \dfrac{d}{dx} (1+ \sec x)^{-1}\\\\\\=3 (-1) (1 + \sec x )^{-1 -1} \dfrac{d}{dx}( 1 + \sec x)\\\\\\=-3(1 + \sec x)^{-2} ( 0 + \sec x \tan x)\\\\\\=-\dfrac{3\sec x \tan x}{(1 + \sec x)^2}$
