1) 4( 10p+6 )+3( 0.5p-0.8)
2) 0.15( 5r +8n)+(0.2r+3.2n)×0.2

Answer 1

1)4*(10p+6)+3*(0,5p-0,8)
40р+24+1.5р-2.4=41.5р+21.6
2)0.15(5r+8n)+(0.2r+3.2n)×0.2= 0.75r+1.2n+0.04r+0.64n=0.79r+1.84n

Answer 2

Упростить:

1) 4(10p+6)+3(0.5p-0.8)
40p+24+1.5p-2.4
41.5p+21.6

2) 0.15(5r+8n)+(0.2r+3.2n)×0.2
0.75r+1.2n+0.04r+0.64n
0.79r+1.84n
