Answer:
a.
b. 
Step-by-step explanation:
You need to remember that:
1. The word "more" indicates Addition.
2. The "Difference" is the result of a Subtraction.
a. Then, knowing this information, you know that:
- "The difference of
and
" must be expressed as:

- Then, "Three more than the difference of
and
" is:

- "The difference of
and
" can be expressed in this form:

Therefore, "Three more than the difference of
and
is equal to the difference of
and
" is:
b. Solve for "s" in order to find its value:

Answer:
It very well could be
Step-by-step explanation:
It could be any type of wood, it doesn't matter weight, volume, or size
Given:
The function is:

It is given that -1 is a zero of the given function.
To find:
The other zeroes of the given function.
Solution:
If c is a zero of a polynomial P(x), then (x-c) is a factor of the polynomial.
It is given that -1 is a zero of the given function. So,
is a factor of the given function.
We have,

Split the middle terms in such a way so that we get (x+1) as a factor.



Again splitting the middle term, we get



For zeroes,
.

and
and 
and
and 
Therefore, the other two zeroes of the given function are
and
.
