The factored expression of the expression x^3 + 4x^2 +5x + 20 is (x^2 + 5)(x + 4)

<h3>How to determine the factors?</h3>

The expression is given as:

x^3 + 4x^2 +5x + 20

Group the expression into two

(x^3 + 4x^2) + (5x + 20)

Factorize each group

x^2(x + 4) + 5(x + 4)

Factor out x + 4

(x^2 + 5)(x + 4)

Hence, the factored expression of the expression x^3 + 4x^2 +5x + 20 is (x^2 + 5)(x + 4)

Answer:

  • 157 in²

Step-by-step explanation:

The area of the shape is the sum of three sections

<u>1. Rectangle</u>

  • A = 5*14 = 70 in²

<u>2. Bigger semicircle</u>

  • A = 1/2π(14/2)² = 76.96 ≈ 77 in² (rounded)

<u>3. Smaller semicircle</u>

  • A = 1/2π(5/2)² = 9.8174 ≈ 10 in² (rounded)

<u>Total area:</u>

  • 70 + 77 + 10 = 157 in²
