Answer:
n = -2 or n = 10
Step-by-step explanation:
n^2 - 8n - 20 = 0
L*w=area
(3x+21)*w=3x^2+33x+84
w=(3x^2+33x+84)/3x+21
(3(x+4)(x+7))/3(x+7)
w=x+4
Answer:
36 people
Step-by-step explanation:
If the yearbook club had 1/2 the participants attend the meeting, than all of them would be represented by 18 x 2, or 36 (since two halves make a whole)
2(3x + 5) (x - 1)
This is done through factoring 2 out of the equation first...
2(3x^2 + 2x -5)
And then cross multiplying it
Answer: 0.04
Step-by-step explanation:
11 gallons divided by 300 miles
11 /. 300 = 0.36666667
