Answer:

C. x^2-6x+9

Step-by-step explanation:

We have the expression (x-3)^2 we can rewrite it as:

(x-3)^2=(x-3)(x-3) and solve it with distributive property or we can use the formula to multiply a binomial by itself. The formula is:

(a+b)^2=a^2+2ab+b^2

or

(a-b)^2=a^2-2ab+b^2

Then:

(x-3)^2=x^2-2.x.3+3^2\\(x-3)^2=x^2-6x+9

The correct option is C. x^2-6x+9

Here is an equilateral triangle. The length of each side is units. A height is drawn. In an equilateral triangle, a line drawn f
Temka [501]

1. Height of the equilateral triangle is: √3 units

2. Area of the equilateral triangle = √3 units²

3. Area = √3/4 x², when each side is x.

<h3>What is an Equilateral Triangle?</h3>

A triangle that has all its three sides equal in length, is referred to as an equilateral triangle.

1. Given the each side measures 2 units, and h is the height, applying the Pythagorean theorem, we would have:

h = √(2² - 1²)

h = √(4 - 1)

h = √3

2. Area of the equilateral triangle = 1/2bh = 1/2(2)(√3)

Area of the equilateral triangle = √3 units²

3. If x is the side length of the equilateral triangle, we would have:

height (h) = √[x² - (x/2)²] = √[x² - x²/4] = √(3x²/4) = √3/2x

Area = 1/2bh = 1/2(x)(√3/2x) = √3/4 x²

We can use ratios to solve

14 students   896 students

----------------- = -------------

1 teacher          x teachers

Using cross products

14 * x = 896*1

Divide each side by 14

14x/14 = 896/14

x =64
