Answer:

45 green marbles

Step-by-step explanation:

Green : Blue : Red = 3 : 7 : 5

Fraction of green marbles = \frac{3}{3+7+5}=\frac{3}{15}

Total marbles = 225

Number of green marbles = \frac{3}{15}*225

                                           = 3 * 15

                                           = 45

Can someone help me with this question
Mashcka [7]
The correct answer here would be D. -1(3x+1)(x+5). You can find this answer by redistributing the problem.

-1(3x+1)(x+5)
-1(3x²+15x+1x+5)
-1(3x²+16x+5)
-3x²-16x-5

Using the math above, we can see that when we redistribute we get the original equation. That makes Choice D correct.

We have to take out the greatest common factor from the given polynomial to factorize the expression. If you observe the terms of the polynomial, the greatest factor that is common to all the terms is 4 x^{4}. So taking it out as common, the factorization of the polynomial will be:

16 x^{9} -36 x^{5}-8 x^{4}  \\  \\ 
=4 x^{4}(4 x^{5}-9x-2)

So the option C gives the correct answer
