Quadratic Formula: (-b +/- sqrt(b^2 - 4ac)) / 2a
2x^2 - 3x = 12
2x^2 - 3x - 12 = 0
a = 2
b = -3
c = -12
(--3 +/- sqrt( (-3)^2 - 4(2)(-12) )) / 2(2)
3 +/- sqrt( 9 + 96 ) / 4
3 +/- sqrt(105) / 4

Answer:
28 miles
Step-by-step explanation:
Let w stand for the number of miles Derrick runs each week. Then after 4 weeks of training, he wants the total mileage to be 100 miles.
16 + 3w = 100
3w = 84 . . . . . . . subtract 16
w = 28 . . . . . . . . divide by 3
Derrick will run 28 miles each week to achieve his training goal.

Answer:
<h2>
A. 1/6^2</h2>
Step-by-step explanation:
6^3/6^6 = 1/216
1/6^2 = 1/36 ≠ 1/216
1/6^3 = 1/216
Answer:
6.11 ft
Step-by-step explanation:
s = (∅/360) * 2πr
s = (35/360) * 2π(10)
s = 6.108652382
Rounded
s = 6.11 ft
