Answer:

  • #1)  3 different roots, total 6
  • #2) 3 different roots, total 9
  • #3) 3 different roots, total 4

Step-by-step explanation:

<h3>#1</h3>

<u>The roots are:</u>

  • x - 3 = 0 ⇒ x = 3, multiplicity 2
  • x + 1 = 0 ⇒ x = -1, multiplicity 3
  • 2x + 5 = 0 ⇒ x = -2.5
<h3>#2</h3>

<u>The roots are:</u>

  • x = 0, multiplicity 3
  • x + 2 = 0 ⇒ x = -2
  • x - 4 = 0 ⇒ x = 4, multiplicity 5
<h3>#3</h3>

<u>The roots are:</u>

  • x² - 1 = 0 ⇒ (x + 1)(x - 1) = 0 ⇒ x = -1, x = 1
  • x² + 4x + 4 = 0 ⇒ (x + 2)² = 0 ⇒ x + 2 = 0 ⇒ x = -1, multiplicity 2

Find the diameter of the object.
Anni [7]

Answer:

1 \frac{1}{5} centimeters

Step-by-step explanation:

The diameter is equal to the radius × 2. We know that the radius is equal to 3/5 centimeters.

To solve this you must do \frac{3}{5} × 2.

This equals \frac{6}{5}, or 1 \frac{1}{5} cm.
