The arrow is pointing at -15 as the final destination, which goes in the final third box.
None of the offered choices is correct.
The radical cannot be simplified. If rewritten, it must be written as something like
or
Step-by-step explanation:
<u>Substitute 86 ⁰F into the given equation:</u>
<u>Subtract 32 from both sides:</u>
<u>Divide each side by 1.8:</u>
If the temperature is 86 ⁰F, that is equivalent to 30 ⁰C.
<u>Substitute 40 ⁰C into the equation:</u>
<u>Multiply:</u>
<u>Add:</u>
If the temperature is 40 ⁰C, that is equivalent to 104 ⁰F.
