B is the correct answer ,,,
3) Multiply the price of the item ($40) by the percent of the sales tax (8%). Then add that to the price of the item to get the total.
=$40 * 8%
=40 * 0.08
=$3.20 tax
=$40 price of item + $3.20 tax
=$43.20 total
5) Multiply the number of students in the band last year (36) by the percentage increased (125%).
=36 * 125%
=36 * 1.25
=45
Hope this helps! :)
The difference of squares is 4m^2 - 20mn + 25n^2
Its a perfect square trinomial.
<h2>What is
perfect square trinomial?</h2>
A perfect square trinomial is the square of a binomial. It follows a pattern when it is factored, so that the first and last terms are perfect squares of monomials and the middle term is twice their product. If the pattern does not fit for a particular trinomial, it is not a perfect square trinomial.
<h3>How to solve this equation?</h3>
(-2m + 5n)^2
(-2m + 5n)(-2m + 5n)
4m^2-10mn-10mn+25n^2
4m^2 - 20mn + 25n^2
Thus, the difference of squares is 4m^2 - 20mn + 25n^2
Its a perfect square trinomial.

Answer:
A
Step-by-step explanation:
A does. There is a gap at zero. A and D are your only real choices. Both show what happens at zero with minor variations and the devil is in the details. D shows that x is open ended when x = 0. That is not correct. The value should be x≥0 so y=2x is closed at x=0.
D is incorrect.
The answer is A.
