Answer:

D.

Step-by-step explanation:

After the third step, take the square root of both sides.

Third Step:

(x+\frac{b}{2a})^2=\frac{b^2-4ac}{4a^2}

Thus, the fourth step is:

\sqrt{(x+\frac{b}{2a})^2}=\sqrt{ \frac{b^2-4ac}{4a^2}} }

The left side cancels:

(x+\frac{b}{2a})=\pm\sqrt{ \frac{b^2-4ac}{4a^2}} }

D.

B. The school prom committee sold presale tickets for
Ivan

Answer:

218 students purchased tickets at the dance.

Step-by-step explanation:

Let,

x be the number of presale tickets

y be the number of tickets sold at the dance

According to given statement;

x+y=334      Eqn 1

18x+24y=7320    Eqn 2

Multiplying Eqn 1 by 18

18(x+y=334)

18x+18y=6012      Eqn 3

Subtracting Eqn 3 from Eqn 2

(18x+24y)-(18x+18y)=7320-6012

18x+24y-18x-18y=1308

6y=1308

\frac{6y}{6}=\frac{1308}{6}\\y=218

Therefore,

218 students purchased tickets at the dance.
