To complete the square you must split the b term in half, then square that answer.

6 is the b term, half of 6 is 3, 3 squared is 9. You will add 9 to both sides of x^2 + 6x = 15

x^2 + 6x + 9 =  24

A winning football team more than doubled. The offensive yards gained by its opponent. The opponent gained 272 offensive yards.
Daniel [21]

Answer:

80x>2*272

More than 6.8 yards per game.

Step-by-step explanation:

Let x be the possible number of yards per play for the winning team.

We have been given that the winning team had 80 offensive plays, so the number of possible yards in 80 offensive plays will be 80x.

We have been given that a winning football team more than doubled the offensive yards gained by its opponent.

We can represents this information in an inequality as:

80x>2*272

Therefore, the inequality 80x>2*272 can be used to find the possible number of x of yards per play for the winning team.

Let us solve for x.

80x>544

Let us divide both sides of our inequality by 80.

\frac{80x}{80}>\frac{544}{80}

x>6.8

Therefore, the winning team will score more than 6.8 yards per play.
