Can someone answer this soon?!?

Sever21 [200]

First get all the terms on the same side:

$x^2 + 7x - 4 = 0$

Now solve using the quadratic formula which is:

$\frac{-b±\sqrt{b^2 - 4ac} }{2a}$

Plug in the values:

$\frac{-7± \sqrt{49-4(1)(-4)} }{2}$

So the answer is:

$\frac{-7 ± \sqrt{65} }{2}$

10 = 43 – |17p + 12|

Kaylis [27]

10=43–|17p+12|

You won't use the absolute sign here. Since you cannot add variable to number AND there are no negatives.

10=43–|17p+12|

10=43–17p+12

Add 12 to 43.

10=43–17p+12

10=55-17p

Add 17p on both sides.

10=55-17p

17p+10=55

Subtract 10 from both sides.

17p+10=55

17p=45.

Therefore, the answer is p=2.64705882353.
