Step-by-step explanation:
2 would represent the Fraction of girls 3 would represent the fraction of boys.
Answer:
x = -0.2 and x = -3.5
Step-by-step explanation:
Combine like terms in the given equation, by subtracting 2x^2 from both sides:
6x^2 + 15x + 3 = 2x^2
-2x^2 = -2x^2
----------------------------------
4x^2 + 15x + 3 = 0
This is a quadratic equation. We'll find the two solutions using the quadratic equation
-b ± √(b^2 - 4ac)
x = ---------------------------
2a
Here the coefficients of the quadratic are a = 4, b = 15 and c = 3.
Thus, the discriminant b^2 - 4ac is 15^2 - 4(4)(3), or +177
and from that we know we'll find two real, unequal roots.
-15 ± √177
The roots are: x = ------------------- , or x = -0.2 and x = -3.5

you take the x and y and take and add numbers till u get the correct numbers. the answer would be x=16 y=5
Volume of a cylinder = pi x r^2 x height.
Using the given information:
410 = pi x 4^2 x height
410 = 50.24 x height
Height = 410/50.24
Height = 8.16 inches
468x^2yz+9yz-2y is your answer
