10. Carolyn says that point \( A \) and point \( B \) represent opposite integers. a. What is the opposite of the integer represented by point \( A \) ? By point \( B \) ?

ind the perimeter of the polygon with the vertices \( G(2,4), H(2,-3), J(-2,-3) \), and \( K(-2,4) \)

Evaluate the expression without using a calculatc \( \log _{2} 1 \) \( \log _{2} 1= \) (Type an integer or a simplified fraction.)

) \( \frac{7}{6}+\frac{2}{4}+\frac{1}{12}= \)

Write the expression in the standard form a + bi. \( (11+i)^{2} \) \( (11+i)^{2}= \) \( ( \) Type your answer in the form \( a+b i \).
