Question

Przekształć iloczyny na sumy algebraiczne:
4(3x-5)=
5(8m+2)=
-2(5t+8)=
-3(2a-7)=
7(2-a-3b)=
-3(5p+2r+1/2)=
2(2a+5-3/4b)=
-2(3b-4a+0,5)=

Answer 1

4 ( 3x - 5 ) = 12x - 20

5 ( 8m + 2 ) = 40m + 10

-2 ( 5t + 8 ) = -10t - 16

-3 ( 2a - 7 ) = -6a + 21

7 ( 2 - a - 3b ) = 14 - 7a - 21b

-3 ( 5p + 2r + 1/2 ) = -3 ( 5p + 2r + 0,5 ) = -15p - 6r - 1.5

2 ( 2a + 5 - 3/4b ) = 2 ( 2a + 5 - 0.75b ) = 4a + 10 - 1.5b

-2 ( 3b - 4a + 0,5 ) = -6b + 8a - 1
