Evaluate the expression when d = 20 and v = 19 20v + 12d - 6v

506

Step-by-step explanation:

First what you would do is replace the v in 20v with 19 like so 20(19) and that would give you 380. Next you would replace the d in 12d with 12(20) and that would give you 240. Then replace the v in -6v with -6(19) and that would give you -114. Add them together and you get 506. The reason why -6x19= -114 is that a negitive times a positive equals a negitive. Or

20v+12d-6v

20(19)+12(20)-6(19)

380+12(20)-6(19)

380+240-6(19)

380+240-114

506
