Name the property of equality or congruence that justifies going from the first statement to the second statement. st=qr qr=st a) reflexive property of congruence b) symmetric property of congruence c) transitive property of congruence d) substitution property of congruence

B is my final answer.

The great thing about this problem is they give you everything you need to solve it easily. so the expression is: 12h+30w12h+30wand so everywhere you have an “h” you place 66. and everywhere you have a “w” you place 33. then the expression will look like this: 12(66)+30(33)12(66)+30(33)from here you multiply and then add. getting the following of: $785,862hope this
