Step-by-step explanation:
The expression x( x - 4 ) when expanded is x² - 4x
An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles.
When a bracket is expanded, each term is multiplied by the expression outside of the bracket.
The distributive property states that multiplying the sum of two or more addends by a number yields the same outcome as multiplying each addend separately by the number and combining the resulting products.
Consider the expression,
x( x - 4 )
Let us assume y = x( x - 4 )
Using the distributive property, a( b + c ) = ab + ac
y = x( x - 4 )
y = x · x - x · 4
y = x² - 4x
Therefore, x( x - 4 ) = x² - 4x
Therefore, the expression when expanded is x² - 4x.

It can be noted that the percentage error made by Allison will be 1.6%
<h3>How to solve the percentage</h3>
From the information given, Allison measured a line to be 19.4 inches long and the actual length of the line is 19.1.
Therefore, the percentage error will be:
= (19.4 - 19.1)/19.1 × 100
= 0.3/19.1 × 100
= 1.6%
In conclusion, the correct option is 1.6%.
