Answer:
x = (5 + √73) / 4 or (5 - √73) / 4
Step-by-step explanation:
2x² - 5x - 6 = 0
x = [5 ± √(25 - 4(2)(-6)] / 2(2)
x = [5 ± √(25 + 48)] / 4
x = [5 ± √(73)] / 4
x = (5 + √73) / 4 or (5 - √73) / 4)
Answer:
Factor out 4 out 8x-12
= 4(2x-3)
I'm not good with intigers, but if you added two negative intigers together wouldn't it still be negative? If you added -1 to -2 you'd get -3. It would always be less than the two original integers.
Answer:
36.4mi
Step-by-step explanation:
The boat sailed two legs of a right-angled triangle.
The distance from the starting point is the hypotenuse of the triangle.
d = √(35² + 10²)
= √(1225 + 100)
= √1325
= 36.4 mi
