Answer:
3
Step-by-step explanation:
We simply start by opening up the bracket
we have this as:
x^2(x-3x) = x^3 - 3x^2
The degree is simply the highest power of x
This is 3
By definition, the span of two vectors is the set of all possible linear combinations of said vectors. So, any element in W is obtaining by choosing two numbers a,b and building

(a)
So, you can show a nonzero polynomial in W by choosing any values of a and b, as long as they're not both zero. To keep it as simple as possible, we can choose for example a=1, b=0 and we obtain one of the base vectors of W:

(b)
Factoring the powers of x, we see that a generic polynomial in W looks like

So, we must build a polynomial

such that it is not possible that

For example, let's try the polynomial 
We should solve the system

And you can check that it has no solutions. So, the polynomial
does not belong to W. On the other hand, it surely belongs to V, because it is a polynomial with degree less than 3. So, the polynomial
belongs to V/W.
Answer:
corresponding angles
the angles are equal
equation: 9x+8 = 4x+18
x=2
angle measurements: 26⁰
Step-by-step explanation:
solve your equation
9x+8 = 4x+18
subtract 4x from each side
5x + 8 = 18
subtract 8 from each side
5x = 10
divide by 5
x = 2
insert x=2 into original equations to make sure you get the same answer.
9(2) + 8 = 26
4(2) + 18 = 26
4p = 2p + 3c....p = popcorn, c = candy bars
c = 6
4p = 2p + 3(6)
4p = 2p + 18
4p - 2p = 18
2p = 18
p = 18/2
p = 9......whoa....9 bucks for popcorn....nothing is cheap anymore
