Question

1) - 4,2х * (-6у)=
2) 8м - 5р - 13м - р=
3) к - (17-к) + (-к + 30)=
4) -6(4+а) + 8(а-6)=

Answer 1

1) -4, 2х • (-6у) =25, 2ху
2) 8m-5p-13m-p=-5m-6p
3) k-(17-k) +(-k+30) =k-(17-k) -k+30= -17 + k+30= 13+k
4) -6(4+a) +8(a-6) = -24-6a+8a-48= -72+2a

Answer 2

1) 25,5ху
2) -5м-6р
3)к-17+к-к+30=к+13
4)-24-6а+8а-48=-72+2а
