(3k+4)(9k+5) the answer should be a polynomial in standard form

27k^2+51k+20

Step-by-step explanation:

Distribute the 3k to both 9k and 5. Then distribute 4 to the 9k and the 5. When you multiply the 3k and 9k it gives you the 27^2. 3k times 5 gives you 15k. 4 times 9k is 35k. 4 times 5 is 20. Combine like terms. 15k plus 35k is 51k. When put in order you get the above answer!

1 is c

2 is a

3 is a

step-by-step explanation:

it's 100

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

  n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the  14th  row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
