Answer:
(x-5)(x+1)
Step-by-step explanation:
Since the highest power of x is 2, u can assume the equation to be (x +/- A) (x +/- B), whereby A and B are unknowns.
Since the coefficient of X^2 is 1, and the number in the equation is - 5, the only possible values for A and B to get - 5 is either - 5 and 1 or 1 and - 5.
Since coefficient of x is - 4 and number in equation is - 5, imagine inserting those numbers in the equation and cross multiplying back. You would realise that the answer should be as listed above.
- The expression was rewritten using the commutative law of addition.
- Line 1 says 3 + 4, which could be represented using dots as ••• + •••• for a total of 7 dots.
- Line 2 says 4 + 3, which could be represented using dots as •••• + ••• for a total of 7 dots.
<h3>What is the
commutative law of addition?</h3>
The commutative law of addition is also referred to as the law of cumulative addition and it states that if two numbers are added together, then, the outcome is equal to the addition of their interchanged position because addition is considered as a binary operation.
This ultimately implies that, the sum of addends would always be the same (equal) regardless of their arrangement in accordance with the commutative law of addition. Mathematically, the commutative law of addition can be represented using the following formula:
A + B = B + A.
In this context, we can reasonably infer and logically deduce that the given expression was rewritten using the commutative law of addition.
In conclusion, Line 1 says 3 + 4, which could be represented using dots as ••• + •••• for a total of 7 dots. Line 2 says 4 + 3, which could be represented using dots as •••• + ••• for a total of 7 dots.

i believe it's 22.5 out of 45 to get exactly .500
Answer:
4 eggs are left.
Step-by-step explanation:
It is actually a tricky question and the trick is that the person, who initially have 6 eggs, has broken two eggs out of them.
Those two broken eggs were then fried and later he ate those.
It is a single incident but in question it appears that 3 different incidents took place in which the person have used all 6.
So actually, he only ate 2 eggs out of 6.
