First, combine like terms.
2x + 3x can combine into 5x
5x = 5
Divide both sides by 5, and you’ll get a final answer of x = 1.
A) set them equal to 180° so it should be 180=5x+10 and x=34 plug it in and VRX=56° and WRV=124°
Answer:
Step-by-step explanation:
First we use product rule
y=x^2lnx
dy/dx = x^2 d/dx (lnx) + lnx d/dx (x^2)
dy/dx = x^2 (1/x) + lnx (2x)
dy/dx = x + 2xlnx
now taking second derivative:
d2y/dx2 = 1 + 2[x (1/x) + lnx (1)]
d2y/dx2 = 1 + 2[1+lnx]
1+2+2lnx
3+2lnx is the answer
