Answer:

B = 4, (y + 4)(y - 4)

Step-by-step explanation:

So both terms are perfect squares. So we want to factor using the difference of squares formula wher a^2 - b^2 = (a + b)(a - b)

a = y and b = 4

Therefore

(y + 4)(y - 4)

Answer:

Draw a dashed line to represent the graph of $5x + 10y = 2000$ and shade the portion below the line for positive values of x and y

Step-by-step explanation:

Let

x------> the number of nickels in the box

y------> the number of dimes in the box

we know that

$0.05x+0.10y < 20\$$

Multiply by $100$ both sides

$5x+10y < 2000$ ------> inequality that represent the situation

The solution of the inequality is the triangular shaded area below the dashed line

see the attached figure

therefore

The statement which best describes the steps to graph the solution to the inequality in x and y is

Draw a dashed line to represent the graph of $5x + 10y = 2000$ and shade the portion below the line for positive values of x and y
