Answer:

Step-by-step explanation:
Consider polynomial
If x=-2 is its zero, then you can divide the polynomial
by
and get

If x=-1, then the polynomial
can be rewritten as

The quadratic polynomial has roots

Then the polynomial
has zeros 
First you combine the like terms which are the Ws.
And if there's no number in front of the variable (w in this case) it
Answer:a) 20%
Step-by-step explanation: 2× 100/ 8+2
Answer:
The equation is, y = 9x + 3.25 and spending $39.25 will give him 4 classes.
So the volume of this prism is equal area of base time length
area of this equilateral triangle with a side of 4 so will be 4*h/2 = 2h
sin60 = h/4
sqrt3 /2 = h/4
4sqrt3 = 2h
h = 2sqrt3
area = 4*2sqrt3 /2 = 4sqrt3
area = 4sqrt3 unit squared
Volume = area time length
V = 4sqrt3 *6 = 24sqrt3 unit cubed
V = 24sqrt3 unit cubed
