1. Given circle O, if m_BAC = 56° and OC = 12 centimeters. Determine the approximate area of sector BC.
Round to the nearest tenth.

In the diagram below? p is circumscribed about quadrilateral abcd. what is the value of x

(mc 02.03) what set of reflections and rotations would carry rectangle abcd onto itself? reflect over the y-axis, reflect over the x-axis, rotate 180° rotate 180°, reflect over the x-axis, reflect over the line y=x reflect over the x-axis, rotate 180°, reflect over the x-axis rotate 180, reflect over the y-axis, reflect over the line y=x

Ireally need subtract and simplify.(-y^2 – 4y - 8) – (-4y^2 – 6y + 3)show your work, ! i will mark you brainliest but you have to show your work.
