Step-by-step explanation:

5x+52=9x+20

subtract 5x on both sides

subtract 20 on both sides

32=4x

divide by 4 on both sides

x=8

plug in x to the equations for A, D, and C

A and D are 92°

C is 56°

B and C will add up to 90, so

90-56=34°

13y-6=34

add 6 on both sides

13y=40

divide by 13

y=40/13 (I don't wanna calculate that)

Differentiate with respect to x : 2xe^x

Gnom [1K]

$\\ \sf\longmapsto \dfrac{d}{dx}2xe^x$

Apply product rule

$\\ \sf\longmapsto \dfrac{d}{dx}2x(e^x)$

$\\ \sf\longmapsto 2x\dfrac{d}{dx}e^x+e^x\dfrac{d}{dx}2x$

$\\ \sf\longmapsto 2xe^x+2e^x$

$\\ \sf\longmapsto 2e^x(x+1)$
