This is an off topic question but i feel the need to let other peoples brains keep running so these are the questions i will give
1.)which expression is equivalent to β4.6+(β0.4)+(β7.2) ?
(4.6+0.4)+(β7.2)
(4.6+0.4+7.2)
β4.6β(0.4+7.2)
β(4.6β0.4)+(β7.2)
2.)which expression is equivalent to β40+(β20)+(β60) ?
β40β(20β60)
β(40β20)+(β60)
β20+(β40)+(β60)
40+20+60
3.) correctly identify the property shown here
β1.4+(β2.6+3.8)=(β1.4+(β2.6))+3.8
4.)correctly identify the property shown here
(β6.8+(β5.1))+6.2=(β5.1+(β6.8))+6.2
5.) use properties of addition to evaluate the expression.
(β64)+((β36)+20)
this is worth 40 pts i will also give brainliest to the one that answers these correctly
