Explanation

 Let’s find the lengths of all three sides using the distance formula:

A(0,4), B(0,0), C(3,0)

AB = √[(0−0)² + (4−0)²] = √[16] = 4

BC = √[(3−0)² + (0−0)²] = √[9] = 3

CA = √[(3−0)² + (0−4)²] = √[9 + 16] = √25 = 5

Perimeter = AB + BC + CA = 4 + 3 + 5 = 12

Explanation

Given:
$x^2 - 3x - 10 = 0$

We are told that one factor is $(x - 5)$.
So, we divide the quadratic by $(x - 5)$ to find the other factor:

Method:
Use factoring:

We want two numbers that multiply to $-10$ and add to $-3$.
These numbers are -5 and 2.

Thus,

$$x^2 - 3x - 10 = (x - 5)(x + 2)$$

Explanation

 Bilateral symmetry is crucial for an active lifestyle as it allows for efficient movement and better sensory perception.

Organisms with bilateral symmetry, such as humans and most animals, have a streamlined body plan that enhances coordination, directional movement, and faster responses to environmental stimuli.

Explanation

 We are given that 78 students represent 30% of the total number of students in the class.

Let's find the total number of students (X).

Using the percentage formula:

So, the total number of students in the class is 260
