Factor 40r–45.
Write your answer as a product with a whole number greater than 1.
whats the answer
The answer is:
5(8r-9)
To factor 40r - 45, we can start by finding the greatest common factor (GCF) of the two terms.
The GCF of 40 and 45 is 5.
So, we can rewrite the expression as:
5(8r - 9).
Therefore, the factorization of 40r - 45 is 5(8r - 9).
To factor the expression 40r - 45, we need to look for the greatest common factor (GCF) between the two terms.
Step 1: Find the GCF of 40 and 45.
To do this, we can list the factors of each number and find their greatest common factor.
Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40
Factors of 45: 1, 3, 5, 9, 15, 45
The GCF of 40 and 45 is 5.
Step 2: Divide each term by the GCF.
40r/5 = 8r
45/5 = 9
So, the expression 40r - 45 can be factored as:
5(8r - 9)
The factored form is a product with a whole number greater than 1, which is 5.
