100% because
is 6 and
is 9 meaning that the sum will come up at 6 or 9 also meaning that its 100%

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
X² + 4x + 3
To solve this quadratic equation, set it equal to zero.
x² + 4x + 3 = 0
Now, you can solve by either using the Quadratic Formula or by factoring. As factoring is much less messy, let us see if this equation is able to be factored.
To factor this standard form equation, find two numbers whose sum is 4 and whose product is 3.
2 + 2 = 4; 2 × 2 = 4 -- This does not work
3 + 1 = 4; 3 × 1 = 3 -- This does work
The factored polynomial is (x + 3)(x + 1). To find x, find the zeros of the factors (set them equal to zero and solve).
x + 3 = 0 => x = -3
x + 1 = 0 => x = -1
Answer:
x = -3
x = -1
