1.)what is the product of (7u+6v)(7u-6v)?
2.)what is the product of (-m+-5n)?

1 (7u+6v)(7u-6v)
 49u^2-42uv+42uv-36v^2
49u^2-36v^2
2.  (-m+5n)(-m-5n)
    m^2+5mn-5mn-25n^2
    m^2-25n^2

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
