Question

MEDAL!!
What is the solution to the inequality below??

Answer 1

\[x^{2}\ge 36\]

Answer 2

\[x^{2}\ge36\]
a) \[x \ge6\]
b)\[-6\le x \le6\]
c)\[x <-6 or x > 6\]
d)\[x \le -6 or x\]

Answer 3

hint:

\[{x^2} - 36 = \left( {x - 6} \right)\left( {x + 6} \right)\]

Answer 4

so we can rewrite your inequality as below:
\[\left( {x - 6} \right)\left( {x + 6} \right) \geqslant 0\]

Answer 5

hint
Square root X^2 and 36. what do you get

Answer 6

i know its 6 but idk the inequalities

Answer 7

that above inequality is equivalent to these systems:
\[\begin{gathered}
\left\{ \begin{gathered}
x - 6 \geqslant 0 \hfill \\
x + 6 \geqslant 0 \hfill \\
\end{gathered} \right. \hfill \\
\hfill \\
\left\{ \begin{gathered}
x - 6 \leqslant 0 \hfill \\
x + 6 \leqslant 0 \hfill \\
\end{gathered} \right. \hfill \\
\end{gathered} \]

Answer 8
