ANSWER TO QUESTION 1
.
EXPLANATION
The function given to us is,

According to rational roots theorem,
are possible rational zeros of
.
We find out that,




Also




This implies that
are factors of
and hence
is also a factor.
We perform the long division as shown in the diagram.
Hence,
.
ANSWER TO QUESTION 2
Sketching the graph
We can see from the factorization that the roots
and
have a multiplicity of 1, which is odd. This means that the graph crosses the x-axis at this intercepts.
Also the root
has a multiplicity of 2, which is even. This means the graph does not cross the x-axis at this intercept.
Now we determine the position of the graph on the following intervals,









We can now use these information to sketch the function as shown in diagram
The general form would be:

where 'a' is responsible for the magnitude of the function, 'b' is responsible for horizontal shift.and 'c' is responsible for vertical shift of the function.
Your answer would be:

Looks like choice A
The common denominator is 28
Since you are blowing warm air, the air molecules are moving fast so it makes the water expand. By the way that's what happens to a thermometer and I think this is a science question :)
This might be right
Answer:
3 avacados for $1.99
Step-by-step explanation:
1.99/3=.66333333 or .66
3.50/5=.7 or .70
since 66 cents is cheaper than 70 cents its a better deal to get the three avacados rather than the 5
