Answer:
The inequality is:
[tex]-20\leqslant x\leqslant45[/tex]Step-by-step explanation:
Let x be the temperature at which the batteries will be stored. We know that this temperature has to be greater than or equal to -20 and less than or equal to 45.
Therefore, the inequality that would describe this situation is:
[tex]-20\leq x\leq45[/tex]
