#c=12#

#"substitute the given values into the equation"#

#30=8+10+clarrcolor(blue)"solve for c"#

#30=18+c#

#"subtract 18 from both sides"#

#30-18=cancel(18)cancel(-18)+crArrc=12#

Substitute the given values into the formula:

[ P = a + b + c ]

Given: ( P = 30 ), ( a = 8 ), and ( b = 10 )

[ 30 = 8 + 10 + c ]

[ 30 = 18 + c ]

[ c = 30 - 18 ]

[ c = 12 ]

The value of the unknown variable ( c ) is ( 12 ).
