Question

ME AJUDEM PFVOR,PARA HOJE,ATÉ AS 18hrs.
EU IMPLORO PFV

Answer 1

Resposta:

a= 8a

b= 8a

c= 4x²

d= 2a+b-5a+3b= 4b- 3a

e= 3am+4am-7m-3m-5= 4am-10m-5

f= 3a-2a+7b-3= a=7b-3

g= 2x³-x²+3-x²-4x²+5x+3= x³-5x²+5x+3

h= 7ab-5a+3-7+3a+ab= 8ab-2a-4

i= 3pq+7p²-8pq+9p²-8pq= 3pq+16p²-16pq= 16p²-13pq

j= 2am-7an+8am-3+an= 10 am-6an-3

k= 2/3 cd +1/5d-2/5c-cd+5/3c=  

2cd/3-3cd/3=1/5d-6c/15+25c/15

10cd-15cd+3d-6c+25c=3d-5cd+19c
