Alright, here's one for Algebra:
Wewaii [24]
Let x= number rows
Then x + 5 = number of seats per row

x(x+5) = 126
X^2 + 5x = 126
x^2 + 5x -126 = 0; now factor or use quadratic:
(x+14)(x-9) = 0; so the answers are either -14, or 9, and since -14 is not possible in this case because you can't have a negative number of rows, the answer is 9 rows.

Check work: number of rows = 9, number of seats per row = 9+ 5= 14, and 9 x 14 = 126

What value of a satisfies the following equation?<br><br> -2(a + 3) = -4a + 32
Yanka [14]

Answer:

a = 19

Step-by-step explanation:

-2(a + 3) = -4a + 32

-2a - 6 = -4a +32

<u> +2a        +2a       </u>

-6 = -2a + 32

<u>-32         -32</u>

-38 = -2a

divide by -2

<u><em>a = 19</em></u>
