First, you need to set the equation equal to zero:
n^2 + 7n + 10 = 0
Now we factor. We need to find two numbers that add up to 7 and multiply to 10.
2 + 5 = 7
2 * 5 = 10
Now, we just need to write this as a polynomial:
(n + 2) (n + 5)
is our answer.
Hope this helps!

Answer:
y^3/4x
Step-by-step explanation:
Given that the expression 6x^2/5y multiplied by some unknown gives answer as 3xy^2/10
We know that if ab = c, the b = c/a
Using the same principle, we have
unknown value = 3xy^2/10 divided by 6x^2/y
Use the fact that a/b divided by c/d = ad/bc
We get unknown = 5y(3xy^2)/6x^2 (10)
=15xy^3/60x^2
Simplify the constant part 15/60 as 1/4
xy^3 /x^2y
X term becomes x/x^2 = 1/x
so multiplying term =y^3/4x
29.9 percent in decimal is 0.299
