Lisa [10]

Answer:

$14.80

Step-by-step explanation:

Tax:

3% of 12 is .4. So she would pay $0.40 for the tax.

Tip:

20% of 12 is 2.4. So she would pay $2.40 for the tip.

Select the correct answer.

Paladinen [302]

Answer:

D

Step-by-step explanation:

$2x^2+16x-8=0$

Simplify:

$x^2+8x=4$

Rewrite in the form $(x+a)^2=b$ :

$x^2+8x=4$

Add $4^2$ to both sides:

$x^2+8x+4^2=4+4^2$

$x^2+8x+4^2=20$

$\left(x+4\right)^2=20$

$x+4=\sqrt{20}$ or $x+4=-\sqrt{20}$

x = -4± $\sqrt{20}$

x= -4± $2\sqrt{5}$
