Consider the expression –3(y – 5)2 – 9 + 7y.
which statements are true about the process and simplified product? check all that apply.

a=the first step in simplifying is to distribute the –3 throughout the parentheses.
b=there are 3 terms in the simplified product.
c=the simplified product is a degree 3 polynomial.
d=the final simplified product is –3y2 + 7y – 9.
e=the final simplified product is –3y2 + 37y – 84.

Option 'B' and 'E' are correct.

Step-by-step explanation:

Since we have given that

Simplification needs a few steps:

So, Option 'B' and 'E' are correct.

As Option 'B' says there are 3 terms in the simplified product, which is true.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
