If $P, Q$ and $R$ are subsets of $A$,then $R \times (P \cup Q) = $

Are the following pair of sets equal? Give reasons.
$A = \{ x : x \text{ is a letter in the word } \text{FOLLOW} \}$
$B = \{ y : y \text{ is a letter in the word } \text{WOLF} \}$

Let $A = \{1, 2, 3, 4, 5, 6\}$. Insert the appropriate symbol $\in$ or $\notin$ in the blank space:
$8 \dots A$

Make correct statements by filling in the symbols $\subset$ or $\not\subset$ in the blank spaces:
${ x:x \text{ is a circle in the plane} } \dots { x:x \text{ is a circle in the same plane with radius } 1 \text{ unit} }$

If $A = \{x, y\}$ then the power set of $A$ is

The solution set of $x \equiv 3 \pmod{7}$,where $p \in \mathbb{Z}$,is given by:
