(n+7)(n-2)
=n•n+(-2)•n+7•n+7•(-2)
=n²-2n+7n-14
=n²+5n-14. In conclusion, the product of (n+7) and (n-2) or (n+7)(n-2)=n²+5n-14. Hope it help!

nikdorinn [45]

You would have to start by doing $120 - $96 for the per-day fee, which leaves Calvin with $24 to spend on miles.

A theater has 22 rows of seats. The first row has 18​ seats, the second row has 20 ​seats, the third row has ​22 seats, and so o
morpeh [17]

Answer:

1078

Step-by-step explanation:

Total no of rows (n) = 22

Since, 18, 20, 22 ..... forms an arithmetic sequence with first term (a) = 18 and common difference (d) = 2.

We need to find: Total no of seats in the theatre (S_{22}).

Formula to be used:

S_{n}= \frac{n}{2}\bigg[2a+(n-1)d\bigg]

Plug the values of a, d and n in the above formula, we find:

\implies S_{22}= \frac{22}{2}\bigg[2(28)+(22-1)(2)\bigg]

\implies S_{22}=11[56+(21)(2)]

\implies S_{22}=11[56+42]

\implies S_{22}=11[98]

\implies S_{22}=1078

Thus, there are total 1078 seats in the theatre.
