Three students were asked to find the value of x in the figure below. The equations they used are
shown. Which students, if any, used a correct equation? Explain the other students' errors and then
find the value of x.

Write a recursive sequence that represents the sequence defined by the following explicit formula:

Does the construction demonstrate how to copy an angle correctly using technology a) yes the distance between points a and f was used to create circle h b) yes the distance between points f and g was used to create circle h c) no the distance between points a and f was used to create circle h d) no the distance between points f and g was used to create circle h

Astudent was asked to find the square of 7x+3. the student quickly wrote (7x+3)^3= 49x^2+9. identify the student's error and provide the correct answer.
