Step-by-step explanation:
(18+44)+22= 18+44+22
18+(44+22)=18+44+22
As there are only +es we can don't put the short lines() and the expressions will still mean the same and they will be equivalent
Answer:
i think it's -46 but i don't know srry if this does not help
Step-by-step explanation:
The answer is a the length is 69 and the base is 115 and if you multiply 115*69 you will get 7935 square units
Answer:
y² + y +
= (y +
)²
Step-by-step explanation:
In most cases, we can factor a polynomial, or quadratic, by looking at the factors of the last term. In this case, the last term is
. When we factor a polynomial, we are looking for two expressions that when multiplied together using FOIL (forward-outside-inside-last) will give us the polynomial. For example: (a + b)(a + b) or (a+ b)².
In order to get y² + y +
, we are looking for a 'c' value that will add up to '1' which is our 'b' value (ay² + by + c).
Since 
Then, we can use
as our factor for both expressions. Putting this together we get: (y +
)(y +
) or (y +
)²
