Answer:

(i)(a - 2y) (3x - 4b)

(iii) (m - n)(m + 4)

Step-by-step explanation:

(i)

3ax - 6xy + 8by - 4ab

= 3x (a - 2y) - 4b (-2y + a)

= 3x (a - 2y) - 4b (a - 2y)

= (a - 2y) (3x - 4b)

(iii)

{m}^{2}  - mn + 4m - 4n \\  \\  = m(m - n) + 4(m - n) \\  \\  = (m - n)(m + 4)

The area of a square garden is 1/ 9 km2. How long is each​ side?
pochemuha

Each side of the square garden is 1/3 km long.

<h3>What is the Area of a Square?</h3>

A square is a four-sided polygon that has all its sides equal to each other in length. To find the area of a square, where a represents the side length of the square, the formula used is: A = a².

Given the following:

Area of the square garden (A) = 1/9 km²

a = side length of the square garden = ?

Plug in the values into the area formula for a square:

1/9 = a²

Take the square root of both sides

√(1/9) = √(a²)

1/3 = a

a = 1/3

Thus, we can state that, each side of the square garden is 1/3 km long.
