8a multiplied by 7a equals 56a². This is because you multiply the coefficients (8 and 7) to get 56, and then you multiply the variable parts (a and a) to get a².

To simplify the expression (6(7a + 2b) + 8a - 8b), first distribute the 6: [6 \cdot 7a + 6 \cdot 2b = 42a + 12b.] Now, combine this with the remaining terms: [42a + 12b + 8a - 8b = (42a + 8a) + (12b - 8b) = 50a + 4b.] Thus, the simplified expression is (50a + 4b).
2a - 4y = 3a - 8a - 5y 7a = -ya = -(y/7)
a2 + 7a - 8a2 = 6a7 ∴ a2 + 7a - 8a2- 6a7 = 0 ∴ a + 7 - 8a - 6a6 = 0 ∴ 7 - 7a - 6a6 = 0 ∴ 6a6 + 7a - 7 = 0
It seems like the question is incomplete, but assuming you meant to ask "What does 6a plus a equal?" In that case, the answer would be 7a, as you are combining like terms by adding the coefficients of the variables. The expression simplifies to 7a because 6a + a = 7a.
The variable is a. You can solve for it, like this: 8a - 9 = 7a - 6 8a = 7a + 3 8a - 7a = 3 a = 3

9a-a = 19+7a 8a = 19+7a 8a - 7a = 19 + 7a - 7a 1a = 19 a = 19
7a+a=8a

The answer would be 8a because... 7a is the same as 7 times a a is the same as 1a. So 7+1=8 and just add on the a
Groups 6A and 7A are typically classified as the "chalcogens" and "halogens," respectively. Group 8A is known as the "noble gases."

No, there is no rest stop southbound between exits 8 and 7a. There is the Molly Pitcher rest stop between exit 8a and 8 and the Richard Stockton service area between 7a and 7 but nothing in between 8 and 7a. for more see http://www.travelboards.com/turnpike/NJ/map.asp
