Answer 1

Ответ:

Пошаговое объяснение:

-4(x+4+y)=-4x-4y-16

-10(2+x+y)=-10x-10y-20

-9(x+7+y)=-9x-9y-63

-3(a+10-b)=-3a+3b-30

15(c-d-3)=15c-15d-45

-12(-x-y+2)=12x+12y-24

3(a-10-b)=3a-3b-30

-19(2-x)+20=-38+19x+20=19x-18

-15(x+4)+60=-15x-60+60=-15x

16-4(2+a)=16-8-4a=-4a+8

-18+8(4-x)=-18+32-8x=-8x+14

29-3(t-8)=29-3t+24=-3t+53

-a+(2a-b)+2b=-a+2a-b+2b=a+b

3b-(18+b)+8=3b-18-b+8=2b-10

Answer 2

To simplify the given expressions, I will distribute the numbers outside the parentheses to the terms inside and combine like terms when necessary.

B) -4(x + 4 + y) = -4x - 16 - 4y

D) (-10)(2 + x + y) = -20 - 10x - 10y

F) -9(x + 7 + y) = -9x - 63 - 9y

B) (-3)(a + 10 - b) = -3a - 30 + 3b

D) 15(c - d - 3) = 15c - 15d - 45

F) (-12)(-x - y + 2) = 12x + 12y - 24

B) 3(a - 10 - b) = 3a - 30 - 3b

D) -19(2 - x) + 20 = 38 - 19x + 20 = -19x + 58

F) -15(x + 4) + 60 = -15x - 60 + 60 = -15x

B) 16 - 4(2 + a) = 16 - 8 - 4a = 8 - 4a

D) -18 + 8(4 - x) = -18 + 32 - 8x = 14 - 8x

F) 29 - 3(t - 8) = 29 - 3t + 24 = -3t + 53

B) -a + (2a - b) + 2b = -a + 2a - b + 2b = a + b

D) 3b - (18 + b) + 8 = 3b - 18 - b + 8 = 2b - 10
