Question

Calcular valor numérico p(x)=5x+3x-2 a x=2b x=5c x=10d x= 12Me ajudem, Por favor !

Answer 1

p(x)=5x+3x-2

a) para x=2
p(x)=5x+3x-2
p(2)=5.2+3.2-2
p(2)=10+6-2
p(2)=16-2
p(2)=14

b) para x=5
p(x)=5x+3x-2
p(5)=5.5+3.5-2
p(5)=25+15-2
p(5)=40-2
p(5)=38

c) para x=10
p(x)=5x+3x-2
p(10)=5.10+3.10-2
p(10)=50+30-2
p(10)=80-2
p(10)=78

d) para x= 12
p(x)=5x+3x-2
p(12)=5.12+3.12-2
p(12)=60+36-2
p(12)=96-2
p(12)=94
