Explanation

Animals are biotic components of the environment because they are living organisms.

Soil, Sun, Water, and Temperature are abiotic components as they are non-living factors that influence ecosystems.

Explanation

In the Cartesian plane, Quadrant II contains points where x is negative and y is positive.

Since (-3, 8) has x = -3 (negative) and y = 8 (positive), it lies in Quadrant II.

Explanation

The fourth root of 256 is:

⁴√256 = ⁴√(4^4) = 4

Explanation

Let's solve the equation:

2(x - 2) - 5(x - 5) = 4(x - 8) - 2(x - 2)

Expanding both sides:

2x - 4 - 5x + 25 = 4x - 32 - 2x + 4

Combine like terms:

-3x + 21 = 2x - 28

Add 3x to both sides:

21 = 5x - 28

Add 28 to both sides:

49 = 5x

Divide by 5:

x = 49/5

Explanation

A composite number is a positive integer that has at least one positive divisor other than 1 and itself.

Let's examine the numbers:

4: divisors are 1, 2, and 4 (composite)

9: divisors are 1, 3, and 9 (composite)

15: divisors are 1, 3, 5, and 15 (composite)

Since all numbers (4, 9, 15) have divisors other than 1 and themselves, they are composite numbers.

The group 4, 9, 15 consists entirely of composite numbers.

Explanation

To factorize the quadratic expression 2x² + 5x + 2, we need to find two numbers whose product is 2 × 2 = 4 and whose sum is 5. These numbers are 4 and 1.

2x² + 5x + 2 = 2x² + 4x + x + 2

= 2x(x + 2) + 1(x + 2)

= (x + 2)(2x + 1)
