D) - y = (x + 5)(x - 3)(x + 1).
<h3>EXPLANATION:</h3>Table in this case would look like this:
Write coefficients of x³, x² ,x and the constant in a row and divisor would be the x value obtained by equation x + 5 = 0.
The sequence of multiplications would be as shown in picture.
x² - 2x - 3
x² - 3x + x - 3
x(x - 3) + 1(x - 3)
(x + 1)(x - 3)(x + 5).

Answer:
Silver
Step-by-step explanation:
Find the volume of the coin
<u>Volume of a cylinder</u>
Given:
- r = 1.5 cm
- h = 0.25 cm
Substituting given values into the formula to find the volume:
Find the density of the coin given it has a measured mass of 18.54 g
<u>Density formula</u>
where:
= density
- m = mass
- V = volume
Given:
- m = 18.54 g
Substituting given values into the density formula:
Given:
Therefore, as the coin is made from silver.
