Answer:
Step-by-step explanation:
2a + 6 / a² -9 = 2(a + 3) / (a² -3²)
= 2(a+3) / (a+3)(a-3) {a²-b² = (a+b)(a-b)
= 2 / (a-3)
Answer:
2,4,6,8,12,16
Because it is 2 times 3 equals 6
2 times 1 equals 2
2 times 2 equals 4
2 times 8 equals 16
2 times 3 equals 6
2 times 4 equals 8
2 times 6 equals 12
and they are all a factor of 2
No, 5/6 is greater.
1) First, you have to get a common denominator, lets use 12
2) To get from 6 to 12 you would multiply times 2
3) Do the same to the numerator(the top number) which is to multiply 5 x 2
4) 5 x 2= 10
5) So, now your fraction has become 10/12
And let me ask you, which is bigger, 10/12 or 2/12
(10/12 is bigger and 2/12 is less)
