Answer:

n = -2

Step-by-step explanation:

Step 1 :

Equation at the end of step 1 :

((0-(8•(n+8)))-6•(7n-3))-54 = 0

Step 2 :

Equation at the end of step 2 :

((0-8•(n+8))-6•(7n-3))-54 = 0

Step 3 :

Step 4 :

Pulling out like terms :

4.1 Pull out like factors :

-50n - 100 = -50 • (n + 2)

Equation at the end of step 4 :

-50 • (n + 2) = 0

Step 5 :

Equations which are never true :

5.1 Solve : -50 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

5.2 Solve : n+2 = 0

Subtract 2 from both sides of the equation :

n = -2

KatRina [158]

Answer:

x^2 - 5x - 66

Step-by-step explanation:

1. Distrubute the x to the x and -11 so you will get x^2 - 11x

2. Distrubute the 6 to x and -11 and you get 6x - 66

3. Combine like terms (x^2 - 11x + 6x - 66) you will get x^2 - 5x - 66

a theater is designed with 15 seats in the first row, 19 in the second, 23 in the third, and so on. if this seating pattern cont

marusya05 [52]

Answer:

<u>131 seats</u> are in the 30th row.

Step-by-step explanation:

The theater is designed with the first row there are 15 seats, in second row 19 seats and in the third row there are 23 seats.

Now, to find the number of seats in the 30th row.

So, we get the common difference( $d$ ) from the arithmetic sequence first:

$19-15=4.$

Thus, $d=4.$

So, the first tem $a(1)$ = 15.

The number of last row ( $n$ ) = 30.

Now, to get the number of seat in the 30th row we put formula:

$a(n) = a(1) + d(n-1)$

$a(30)=15+4(30-1)$

$a(30)=15+4\times 29$

$a(30)=15+116$

$a(30)=131$

Therefore, 131 seats are in the 30th row.
