Answer: 7/4
Step-by-step explanation: because you simplify
Factorising an equation is putting it into bracket form.
This has square numbers and so needs double brackets
(5x - y) (5x+y)
If you then check this by multiplying the brackets out again you will get:
5x^2 - 5xy + 5xy - y^2
The positive and negative 5xy's cancel each other out and you are left with its original form. Your answer is
(<span>5x - y) (5x+y)</span>

Answer:
432.7 mens ate there in class
Answer:
Victor's equation did not correctly model the problem.
The equation that correctly modeled the problem:
$129.85-$89.25=$40.60
Step-by-step explanation:
The amount required for bicycle purchase by Victor is $129.85 out of which $89.25 has been saved,in other words,the balance required for Victor to reach his target purchase price is the difference between the total cost of $129.85 and the $89.25 already saved.
The balance required=$129.85-$89.25=$40.6
This shows that the equation put forward by Victor is wrong.
An equation that correctly represents the problem is the difference between the target savings and the amount already saved as stated above
