Question

como resolve essas expressoes algebricas?? a) -9d+(-5d)=?? b) 3h-(-5h)=?? c) -3a-4a-a-a-3a=??? d) p+8p-(-2p)+(-3P) =??? e) a+5b+7a-b-b=???? me ajudem pfvr!!!

Answer 1

a) -9d+(-5d)=  - 9d - 5d ==> - 14d

b) 3h-(-5h)= 3h+ 5h =  8h

c) -3a-4a-a-a-3a=  - 12a

d) p+8p-(-2p)+(-3P) = 9p + 2p -3p = 8a

e) a+5b+7a-b-b= a+7a + 5b-b-b ==> 8a + 3b
