Answer: 38
Step-by-step explanation:
To solve this problem, you are simply going to plug in the values for the numbers into the equation so it would look like this:
7(3)+8(4)-5(6)

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.
ANSWER: Paige's unit rate for filling the bucket, in gallons per minute (gpm) is 1.5
EXPLANATION: Based on the given fractions, we need to divide 3/8 by 1/4. Divide by its reciprocal: 3/8 * 4. Cross out the common factor, 3/2. Then, obtain the result, 1.5 GPM.
Answer:
1. 9461000000000
move the desimal in 9.461 12 places to the right to get:
9461000000000
2.
5.85 x 10^-3,
2.5 x 10^-1,
3.6 x 10^8,
8.5 x 10^8,
8.5 x 10^12
the smallest exponent is the smallest. Since 8.5 x 10^8 and 3.6 x 10^8 have the same exponent, go to the desimal
Answer:
3/9
Step-by-step explanation:
Common denominator: 27
24/27 - 9/27 = 15/27 = 3/9
