No, 42 is a multiple of 3. 3 is a factor of 42.
The greatest common factor is 7a.21ab+35a=7a(3b+5)GCF(21ab, 35a) = 7a. How? Factor out each term to get:21ab = 3 x 7 x a x b35a = 5 x 7 x aThe factors that occur both in 21ab and 35a are 7 and a. Therefore, the GCF is 7a.
factor of 36- 1,2,3,4,6,9,12,18,36 factor of 42- 1,2,3,6,7,14,21,42
Since 3 is a factor of 42, it is automatically the GCF.
The greatest common factor of 42 and 66 is 6.6
The GCF is 7a.
Since 7a is a factor of 14ab, it is automatically the GCF.
7a 7a * 4 = 28a 7a * 7b = 49ab
To factorize the expression 7a^2 - 8ab, you need to find the greatest common factor of the two terms. In this case, the common factor is a. So, you can factor out an 'a' to get a(7a - 8b) as the factored form of the expression. This means that 7a^2 - 8ab can be simplified as a multiplied by the quantity (7a - 8b).
Yes.
7a + 6 = -36 Subtract 6 from both sides: 7a = -42 Divide both sides by 7: a = -6 a = -6
7a2
7a
(5a + 2)(a + 1)
42, because if there is nothing between the 7 and 'a' and 'a' equals 6 then the answer is 42.
6 is a factor of 42.
28 is not a factor of 42.
