Answer:

3 more red marbles

Step-by-step explanation:

When you add up all of the marbles, there are 13 marbles.

The objective is to have the probability of selecting a blue marble from the bag to be 1/4. Since there are 4 blue marbles and 4 is 1/4th of 16, 16-13 is 3 so you add 3 more red marbles to have that chance.

I hope this helps!!!

kicyunya [14]
Here is your great answer Simplifying
4x2y + 12xy2 + 9y3

Reorder the terms:
12xy2 + 4x2y + 9y3

Factor out the Greatest Common Factor (GCF), 'y'.
y(12xy + 4x2 + 9y2)

Factor a trinomial.
y((2x + 3y)(2x + 3y))

Final result:
y(2x + 3y)(2x + 3y)

Greatest common factor of −27x2yz5 + 15x3z3
dimulka [17.4K]
The GCF will be found as follows:
-27x^2yz^5+15x^3z^3
-27x^2yz^5=-3*3*3*x*x*y*z*z*z*z*z
15x^3z^3=3*5*x*x*x*z*z*z
the GCF is the product of the lowest power of each factor that appears in each term
thus we shall have:
3*z*z*z*x*x
=3z^3x^2
