Factoring

Step-by-step explanation:

(x+4)² = 15

x² + 8x + 16 = 15

x² + 8x + 1 = 0

$x = \frac{ - 8 + \sqrt{64 - 4} }{2} = - 4 + \sqrt{15} \\ \\ x = \frac{ - 8 - \sqrt{64 - 4} }{2} = - 4 - \sqrt{15}$

I hope this helps you :)

hello!

the slope is $\frac{-42}{0} = \frac{21}{32} = 0.65625$

which makes the slope -42

to get this, use the following equation: $\frac{y_{2} - y_{1} }{x_{2} - x_{1} }$

in this case, the equation variable substitutions are as follows

$\frac{(-19) - (23)}{(-32) - (-32)} = \frac{-42}{0}$

i hope this , and have a nice day!
