Need help on number 6 and 13 plz
Ivahew [28]

Answer:


Step-by-step explanation:

6A) Death Valley is located below sea level.  It says it is -282 feet.  This means that it is below 0 and sea level is marked at 0.

6B) 5280 + 282 = 5562 ft higher

6C)  The closer you get to the ocean the closer you are to 0.  If you were in the water floating on top you would be at 0.

13) all 3 are 28

The parenthesis have to stay.  This is how we know to distrubute the 2 across the problem.

igomit [66]

Answer:

\large\boxed{x=-\dfrac{7-\sqrt{97}}{4}\ \vee\ x=-\dfrac{7+\sqrt{97}}{4}}

Step-by-step explanation:

ax^2+bx+c=0\\\\\Delta=b^2-4ac\\\\\text{if}\ \Delta0,\ \text{then an equation has two solutions:}\ x=\dfrac{-b\pm\sqrt\Delta}{2a}\\\\\text{We have:}\\\\-2x^2-7x+10=4\qquad\text{subtract 4 from both sides}\\\\-2x^2-7x+6=0

a=-2,\ b=-7,\ c=6\\\\\Delta=(-7)^2-4(-2)(6)=49+48=97>0\\\\\sqrt\Delta=\sqrt{97}\\\\x=\dfrac{-(-7)\pm\sqrt{97}}{2(-2)}=\dfrac{7\pm\sqrt{97}}{-4}=-\dfrac{7\pm\sqrt{97}}{4}
