Add 121/4 to each side:
x²+11x+121/4 < 121/4-8
x²+11x+121/4 < 89/4
(x+11/2)² < √89/2 ⇒ -√89/2 < x+11/2 < √89/2
-11/2-√89/2 < x < -11/2+√89/2

Which inequalities are true? Check all that apply. Three-fifths &lt; 0 Four-sixths greater-than one-half Nine-elevenths &lt; 1 T
Kipish [7]

\frac{3}{5} < 0

\frac{8}{16} > \frac{1}{2}\\\\

<em><u>Solution:</u></em>

<em><u>We have to find the inequalities that are true</u></em>

<em><u>Option 1</u></em>

\frac{3}{5} < 0\\\\0.6 < 0

0.6 is not less than 0

Thus this inequality is not true

<em><u>Option 2</u></em>

\frac{4}{6} > \frac{1}{2}\\\\0.667 > 0.5

0.667 is greater than 0.5

Thus this inequality is true

<em><u>Option 3</u></em>

\frac{9}{11} < 1\\\\0.818 < 1

0.818 is less than 1

Thus this inequality is true

<em><u>Option 4</u></em>

\frac{8}{16} > \frac{1}{2}\\\\

0.5 = 0.5

Thus the above inequality is not true
