Answer:
The answer to your question is: letter A
Step-by-step explanation:
(x + 3) (3x² + 8x + 9) = 3x³ + 8x² + 9x + 9x² + 24x + 27
= 3x³ + 17x² + 33x + 27 Simplify like terms
Α. 3x3 + 17x2 + 33x + 27
Β. 3x3 + 17x2 – 15x + 27
C. 3x2 + x2 + 33x+ 27
D. 3x3 + 17x2 + 33x - 27
14+14=28
48-28=20
20 divided by 2 =10
The width is 10

Answer:
See below in bold.
Step-by-step explanation:
Note that the numerators are the squares of 1, 2 3, 4 ...... and the denominators are the squares of 2, 3, 4, 5.....
The next 2 terms are 25/36 and 36/49.
The nth term is n^2 / (n + 1)^2 where n is the sequence number.
The 10th term is 10^2 / 11^2
= 100/121.
