What is the gcf of 21 30 anwhat is the gcf of 21 , 30 ,and 44?

Ymorist [56]

Find the prime factorization of each value.

21 is 7*3

30 is 3*10 which can be further broken down into 3*2*5

44 is 4*11 which can be further broken down into 2*2*11

What do they share in common?
21 and 30 each have a 3 in common.
Therefore the GCF(21, 30) = 3.

21 and 44 share a 2 in common.
But if we're looking at all three of them together, they share nothing in common.

Ella completed the following work to test the equivalence of two express

murzikaleks [220]

Answer:

The expressions are not equivalent because Ella did not know that you can’t use substitution to test for equivalence.

Step-by-step explanation:

<u>Equivalent algebraic expressions</u> are those expressions which on simplification give the same resulting expression.

Two algebraic expressions are said to be <u>equivalent</u> if their values obtained by substituting any values of the variables are same.

Two expressions 3f+2.6 and 2f+2.6 are not equivalent, because when f=1,

$3f+2.6=3\cdot 1+2.6=3+2.6=5.6\\ \\2f+2.6=2\cdot 1+2.6=2+2.6=4.6\\ \\5.6\neq 4.6$

Method of substitution can only help her to decide the expresssions are not equivalent, but if she wants to prove the expressions are equivalent, she must prove it for all values of f.

$3f+2.6=2f+2.6\\ \\3f=2f\\ \\3f-2f=0\\ \\f=0$
