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.

Answer:
<h3>15%</h3>
Step-by-step explanation:
<h3>First , We will solve their daily Income </h3>
• Income = spends / rate
• Income = 600 / 40%
• Income = 600 / 0 .40%
• Income = 1500
Thus , Their daily Income is 1500 . Now ,We will solve for the rate of the Allowance .
• Rate = spent / Income
• Rate = 225 / 1500
• Rate = 0.15
• Rate = 15%
Therefore, the percent of the family's daily Income of the Allowance of their children's is 15%

Answer:
The number would be 3.
Step-by-step explanation:
This problem can be written as
5x + 9 = 24
So to solve it, you have to isolate x:
5x + 9 = 24
5x + 9 - 9 = 24 - 9
5x = 15
5x÷5 = 15÷5
x = 3
Check:
5(3) + 9
= 15 + 9
= 24
