12. On addition, you can just combine like terms.
2v^3+(-v^3)=v^3
-v+v cancels each other out
8+(-3)=5
So you have v^3+5
14 On subtraction, you have to remember to distribute the negative sign so after you do that you have:
4h^3+3h+1+5h^3-6h+2
Then you can combine like terms
4h^3+5h^3=9h^3
3h-6h=-3h
1+2=3
So you end up with:
9h^3-3h+3

Answer:
In mathematics, a conic section is a curve obtained as the intersection of the surface of a cone with a plane. The three types of conic section are the hyperbola, the parabola, and the ellipse; the circle is a special case of the ellipse, though historically it was sometimes called a fourth type.
Conic sections are formed on a plane when that plane slices through the edge of one or both of a pair of right circular cones stacked tip to tip.
The magnitude size of -5.8 is 5.8
magnitude size of a number is the number itself, and if it’s negative, it becomes its absolute value (in other words, you remove the subtraction sign).
Your equation is already in one of the standard form. Specifically, the slope intercept form.
y=mx + b.
m is the slope, b is the intercept.
Start with the intercept y= 2, the point (0,2).
A slope of 3 would give you (1,5) as a second point for your line.
Get a ruler and draw a line through the two points.
1) you have to add all the rings together to find the denominator
6 + 11 + 15 + +3 = 35
2) the numerator is the amount of rings of the certain color you are trying to find the probability of
15
3) find the theoretical probability! 15/35
4) simplify
15/35 (divide both by 5) = 3/7
hope it helped :)
