Question

Evaluate the expression which r=-1, n=3, t=12, v=0 and w=1 -1/29/19

Answer 1

To evaluate the expression

`r=1\text{ , n=3 , t= 12 , v = 0 , w= }(-1)/(2)`

`(9)6r+2n\text{ = 6(1)+2(3)=6+6= 12}`
`(10)\text{ w(n-r) = }(-1)/(2)(3-1)=(-1)/(2)(2)=-1`
`(13)(4n)^2=(4x3)^2=12^2=144`
`(15)\text{ 2(3r+w) = 2(3 x 1+-}(1)/(2))=2(3-(1)/(2))\text{ = 2(}(5)/(2))=5`
