Answer:
1) It would be about a 55% increase. 2) It would be about a 79% increase
Step-by-step explanation:
I used process of elimination to figure out how much of a percentage would be needed by just multiplying 210 by different percentages until I found the answer.
Sorry I don't have like a definite formula or anything for you to figure these questions out... I hope someone else answers with a more definite answer!
Using the factor theorem, it is found that the polynomial is:

Given by the first option
---------------------------
Given a polynomial f(x), this polynomial has roots
using the factor theorem it can be written as:
, in which a is the leading coefficient.
---------------------------
In this question:



- By the options, leading coefficient

Thus:



Which is the polynomial.

480/6<span> = 80ft </span>7<span> x 80 = 560ft.</span>
I would add like terms, meaning subtract 6.4 from both sides.
3.5n = 36.1
