The answer is 62.5 minutes because...
40 question would be 50 minutes and then you still have 10 more so divide 25 by 2 to get 12.5
Finally add everything together (25+25+12.5=62.5)
50+200+40=254 that is the simplest one I could think of
Answer:
the thrid one
Step-by-step explanation:
All the tax comes out of $235 So it would be 6.2% from 235 3% from 235 And 1% from 235 So if you at all the percents together You get 10.2% Which is 23.97 In tax plus the 36 Minus off of the 235 It makes net pay 175.03

Answer: You have the correct answer. It's choice A. </h3>
Explanation:
You can verify this by plugging each root into the equation.
So for instance, plug in x = -2 and we get
f(x) = -3*(x+2)*(x-sqrt(3))*(x-4)
f(-2) = -3*(-2+2)*(-2-sqrt(3))*(-2-4)
f(-2) = -3*(0)*(-2-sqrt(3))*(-2-4)
f(-2) = 0
This verifies x = -2 is a root.
All that matters is that zero buried in there in the second to last step. Multiplying 0 by anything leads to 0. The other roots are verified in the same manner. The -3 out front is the leading coefficient.
----------------
Extra info:
- Choice B is eliminated because (x+3) being a factor implies that x = -3 is a root. But this isn't listed in the instructions.
- Choice C is a similar story to choice B
- Choice D is eliminated since -sqrt(3) is not one of the listed roots, so (x+sqrt(3)) is not a factor.
