Simplify 21 a +(-18b)-6a+11b

Is -24 a solution to the equation -16+2x=-64

Write two point-slope equations for the line passing through the points (6, 5) and (3, 1)

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
