Question

use the distributive law to expand the following
6(y+8)

7(l+4)

8(s+7)

4(2+a)

7(x+5)

3(6+a)

9(9-x)

5(j-4)

Answer 1

6(y+8) = 6*y + 6*8 = 6y + 48

7(l+4) = 7*l + 7*4 = 7l + 28

8(s+7) = 8*s + 8*7 = 8s + 56

4(2+a) = 4*2 + 4*a = 8 + 4a

7(x+5) = 7*x + 7*5 = 7x + 35

3(6+a) = 3*6 + 3*a = 18 + 3a

9(9-x) = 9*9 - 9*x = 81 - 9x

5(j-4) = 5*j - 5*4 = 5j - 20
