Answer:
2. a1 = 10 and an = a(n-1) + 2
Step-by-step explanation:
10 is our first term so it would be a of 1.
Then, in this arithmetic sequence, it is increasing by 2.
So, therefore our recursive formula for this arithmetic sequence would be:
a(n) = a(n-1) + 2
Answer:
To find the missing side we need to calculate the sum of the two given sides and then subtract that from the perimeter.
7a - 11b - (2a + b + a - 9b)
= 7a - 11b - (3a - 8b)
= 7a - 3a - 11b + 8b
= 4a - 3b
Answer:
The equivalent expression would be 3^6, and without exponents this would be equal to 729.
Step-by-step explanation:
To get the equivalent expression, you have to know that terms with the same base that are multiplied simply add together exponents.
3^4 * 3^2 = 3^6
Then we can find that by expanding the terms and completing the multiplication.
3 * 3 * 3 * 3 * 3 * 3 = 729
I believe you just distribute it so, multiply each one in the parenthesis (2v+3)
6vx2v=12v
6v x 3= 18v
so it becomes 12v+18v
then add 12 + 18 I think
