5x = 300
x = 60
So, the area of Mr. Idris' apple orchard is (x)2 = (60)2 = 3,600 unit area
Get to know the properties of arithmetic operations on algebraic forms
The operation of addition and multiplication of algebraic forms has several properties,
including:
1. Commutative Properties
a + b = b + a
a × b = b × a
(Already shown before)
2. Associative Properties
a + (b + c) = (a + b) + c
a × (b × c) = (a × b) × c
(Please check)
3. Distributive Properties (multiply to addition)
a × (b + c) = a × b + a × c
or a(b + c) = ab + ac
Example 3.1 Multiplication of Algebraic Forms
Simplify the following algebra
1. 2a x 2b = …
2. 2(3 + 1) = …
3. −6(2 − 3) = …
Solution:
1. 2a x 2b = 4ab
