Answer:
<h2>Width of the rectangle is 2</h2>
Step-by-step explanation:
A rectangle can is made up of two right angled triangle as shown.
Since area of a rectangle = 
Area of one of the triangle = 
The length and width of the triangle will be the same as that of the rectangle i.e 5units long and 2units wide
Area of one of the triangle = 
Area of one of the triangle = 5units²
The area of the triangle above will equal one half of a rectangle that is 5 units long and 2 units wide.
The model shows that we are to arrange the factors based on the terms in the square box. The factored form is(6x+5)(x-4)
<h3>Factorizing quadratic equations</h3>
Factorization is a way of simplify. Given the equation 6x² - 19x - 20
Factorize
6x² - 19x - 20
6x² - 24x + 5x- 20
6x(x-4)+5(x-4)
(6x+5)(x-4)
We are to arrange each term of the factors in the square box

The expression which is equivalent to √(-9) is 3i.
<h3>What is Complex number?</h3>
A complex number is the sum of a real number and an imaginary number. A complex number is of the form a + ib and is usually represented by z.
Here, given expression;
y = √(-9)
y = √9 X √(-1)
y = 3√(-1)
y = 3i
Thus, the expression which is equivalent to √(-9) is 3i.
