Answer:

C. (3x)^2 - (2)^2

Step-by-step explanation:

Each of the two terms is a perfect square, so the factorization is that of the difference of squares. Rewriting the expression to ...

(3x)^2 - (2)^2

highlights the squares being differenced.

We know the factoring of the difference of squares is ...

a^2 -b^2 = (a -b)(a +b)

so the above-suggested rewrite is useful for identifying 'a' and 'b'.

write a conjecture as to the number of sides as compared to the number of triangles formed when drawing diagonals from one verte

zmey [24]

Answer:The Collatz conjecture is a conjecture in mathematics that concerns a sequence defined as follows: start with any positive integer n. Then each term is obtained from the previous term as follows: if the previous term is even, the next term is one half the previous term. If the previous term is odd, the next term is 3 times the previous term plus 1.

Step-by-step explanation :an opinion or conclusion formed on the basis of incomplete information.

Julie and Tim are both cable subscribers. Julie pays 70$ per month plus an additional $4.25 for each movie she orders. Tim’s pay

Nikolay [14]

Answer:

Julie's bill came to $121 for the month in which she ordered 12 movies.

Step-by-step explanation:

Let x represent the number of movies ordered.

Julie: $70 + ($4.25/movie)x, and ...

Tim: $49.50 + ($5.50/movie)x

If Julie ordered 12 movies last month, then her bill came to

$70 + ($4.25/movie)(12 movies) = $70 + $51 = $121

Please be clearer about what you want here. Are you refering to Julie or to Tim or to both when you write, "an equation that best represents the amount of movies?"
