Answer: 168
Step-by-step explanation:
1. -9 * 14 = -126
2. -126/ -0.75 = 168
2f'(x)+2x(f(x))^3+3x^2(f'(x))=0
f(3)=-2, x=3
2f'(3)+2*3*-2^3+3*-2^2*f'(3)=0
2f'(3)-48+12f'(3)=0
14f'(3)=48
f'(3)=48/14=24/7
12.1 per second or 12.1 • 60 seconds or a minute is 726

Step-by-step explanation:
2x^3-42x-40=0
2x^3-42x=40
2x(x^2-21)=40
a. 2x=40=>x=20
b. x^2=21+40=>x^2=61=>x=+-(radical(61)
