Factor 81-27p is
A)9(9-3p)
B)27(3-p)
C)27(54-p)
D)27(p-3)
I think A but not sure. Is there a website that explains simplifying Algebraic Expressions? Thanks for your help.

A is a factored result, but it isn't factored completely.
Notice that 9 - 3c still contains a common factor of 3, so you have to factor until you end up with a result that no longer contains any common factor
so,
81 - 27p
= 27(3 - p) , which is B
you can always check your answer but expanding it
Notice that both A and B give you the original result.
Most textbooks label these type of questions with:
Factor fully , or, factor completely so you must arrive at a "best" answer.
81 = 27 ∙ 3
81 - 27 p =
27 ∙ 3 - 27 p =
27 ( 3 - p )
Answer B
In google type:
simplifying algebraic expressions
you can find many sites
1.
a. y and 1.2y
2. 12x + 11
3.
c. 15y + 14
4.
b . 27 (3 - p)
I got a %100
For ppl at Connections Academy :)
good answer jayden
you get a 75% so a c
conexis student is correct but you have to go to conexues

@bonququi what is wrong wif you btw does any one knows for the Writing & Evaluating Algebraic Expressions Quiz Part 2
To factor the expression 81-27p, we can look for the greatest common factor (GCF) of the terms. The GCF of 81 and 27p is 27, so we can rewrite the expression as:
81 - 27p = 27(3) - 27p
Factoring out the GCF, we get:
81 - 27p = 27(3 - p)
Therefore, the correct factored form of 81 - 27p is option B) 27(3 - p).
For learning more about simplifying algebraic expressions, there are several websites that can be helpful. One popular website is Khan Academy (khanacademy.org), which offers free video lessons and practice problems for various math topics, including simplifying algebraic expressions. Another useful website is MathisFun (mathisfun.com), which provides clear explanations and examples for simplifying algebraic expressions and other math concepts.
