Answer:
2x5y2−8x4y2−18x3y2+5x2y2−20xy2−45y2
Step-by-step explanation:
y2(2x3+5)(x2−4x−9)
=(y2(2x3+5))(x2+−4x+−9)
=(y2(2x3+5))(x2)+(y2(2x3+5))(−4x)+(y2(2x3+5))(−9)
=2x5y2+5x2y2−8x4y2−20xy2−18x3y2−45y2
=2x5y2−8x4y2−18x3y2+5x2y2−20xy2−45y2

You can set each equation to 0 so it would look like this:
And solve
4n+5=0. 3n-7=0
-5=-5. +7=+7
4n = 5. 3n = 7
4n/4 = 5/4. 3n/3 = 7/3
n = 5/4 n = 7/3
The first set of answers are the correct answers for n.
Ok so first find the number of cats. Since it says there are done the number of cats to dogs we need to multiply 30 times 2, which equals 60. So now we know there are 60 cats, 30 dogs and 40 birds. Add up all the animals to get 130 animals total. Next divide 30 by 130 to get the percentage. Leave a comment if you need more help.
Answer:
Step-by-step explanation:
the fraction is right, but notice that the numerator and denominator are both divisible by 16.
64 divided by 16 is 4,
80 divided by 16 is 5.
The answer would be (A) The quotient of 2 and the sum of 3 and y
