Question

Determine a equação P= 4.(n+5)+4.(n+2)+4.(n+1)+2.(n+8)+2.(n+14)+2.(n+22)+2.(n+10)

Answer 1

$P=4*(n+5)+4*(n+2)+4*(n+1)+2*(n+14)+2*(n+22)+2*(n+10)\\\\P=4n+20+4n+8+4n+4+2n+28+2n+44+2n+20\\\\P=18n+124$

Answer 2

p=4(n+5)+4(n+2)+4(n+1)+2(n+8)+2(n+14)+2(n+22)+2(n+10)

Distribuir:

p=(4)(n)+(4)(5)+(4)(n)+(4)(2)+(4)(n)+(4)(1)+(2)(n)+(2)(8)+(2)(n)+(2)(14)+(2)(n)+(2)(22)+(2)(n)+(2)(10)

p=4n+20+4n+8+4n+4+2n+16+2n+28+2n+44+2n+20

Combinar termos semelhantes:

p=4n+20+4n+8+4n+4+2n+16+2n+28+2n+44+2n+20

p=(4n+4n+4n+2n+2n+2n+2n)+(20+8+4+16+28+44+20)

p=20n+140
