Which expression is equivalent to −2.6+(−2.9)+(−7.1) ? a) −(2.6−2.9)+(−7.1)b) (2.6+2.9)+(−7.1)c) −2.6+(2.9+7.1)d) −(2.6+2.9+7.1)

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
