12x^3 +2x^2-30x = 8
2x( 6x^2 +x -15) = 8
so 2x= 8, x=4
(2x) ( 2x-3) ( 3x+5) = 8
2x-3 = 8
2x= 11
x= 5.5
3x+5=8
3x= 3
x=1

Work backwards.
After she put half of what she had left in, she had 17.76.
Multiply by 2:
17.76 * 2 = 35.52
Add 25:
35.52 + 25 = 60.52
Add 14.48:
75
So she received $75 on her birthday.
There are two positive slopes on the opposite side for E and F, while there are two negative slopes on the opposite sides for G and H.
Answer:
30 seats
Step-by-step explanation:
To answer this question, we will be assigning values for both rows and seats.
R = Rows
S = Seats
Remember that rs = 600
r = s - 10, plug this equation into rs = 600, and factor it:
s(s-10) = 600
s^2-10s-600 = 0
(x-30)(x+20) = 0
There are 30 seats in the row. To determine which one is your answer, your answer MUST be positive because it is impossible to have negative seats. (x-30) is 30, which is the positive value found when factoring.
