The distributive property combines multiplication and addition.
It uses multiplication to combine the simple numbers with addition.
An example is that if we wanted to multiply 15 and 12, we can multiple 15 and 10 and 15 and 2 and then we add them.
The length of the shorter piece is 30
<h3>What are algebraic expressions?</h3>
Algebraic expressions are expressions that are made up of constants, terms, factors and variables.
They also contain mathematical operations such as division, addition, multiplication, subtraction, etc
From the information given, we have;
Let the length of one piece be x
Let of the other piece is 5x
5x + x = 180
collect like terms
6x = 180
Make 'x' the subject
x = 180/ 6
x = 30
Thus, the length of the shorter piece is 30
