${x}^{2} - 4x - 9 = 29 \\ {x}^{2} - 4x - 38 = 0 \\ \\ x12 = \frac{ - b \frac{ + }{ - } \sqrt{d} }{2} \\ d = {b}^{2} - 4ac \\ d = 16 + 152 = 168 \\ \\ x1 = \frac{4 - \sqrt{168} }{2} \\ x2 = \frac{4 + \sqrt{168} }{2}$

1-2n) - 7n(12-2) simplify this and show work

Natasha2012 [34]

For this case we must simplify the following expression:

$(1-2n) -7n (12-2) =$

We solve the operation of the second parenthesis, taking into account that different signs are subtracted and the sign of the major is placed:

$(1-2n) -7n (10) =$

We multiply:

$(1-2n) -70n =$

We eliminate the parentheses:

$1-2n-70n =$

We add similar terms, taking into account that equal signs are added and the same sign is placed:

$1-72n$

Answer:

The simplified expression is: $1-72n$

leona has three dollars less than skye. together they have 17 dollars. how much money does skye have?

Fynjy0 [20]

L has "x -3"
S has "x"

x + x - 3 = 17

2x -3 (+3) = 17 (+3)

2x = 20

2x/2 = 20/2

x = 10

Leona has x - 3, or 10 - 3, or 7 dollars
Skye has 10 dollars
