Answer 1

The answer would be: <

Explanation:

I took the quiz.

(there should be photo proof)

Answer 2

On the left side we have:

`18-18=0`

Then, on the right side:

`\begin{gathered} 2\cdot\mleft\lbrace28-3\cdot(2+4\mright)\}=2\cdot\mleft\lbrace28-3\cdot(6\mright)\} \\ =2\cdot\mleft\lbrace28-18\mright\rbrace=2\cdot10=20 \end{gathered}`

Therefore, since in the left side we have 0 and on the right side we have 20, the correct symbol would be < and the expression would be:

`18-18<2\cdot\mleft\lbrace28-3\cdot(2+4\mright)\}`
