Sagot :

1.) (9*2)-(9*-1)
2.)4*(9+1)
3.)A:GCF=5
B:5*(20-15)
4.) 7x+14

Answer:

Step-by-step explanation:

18) 9*(2-1)  = (9 * 2) - (9*1)

19) (4*9) + (4*1) = 4*( 9+ 1)

20)  a) 20 = 2 * 2 * 5

          15 =   3 * 5

GCF = 5

20 - 15 = (5*4) - (5*3)

            = 5*(4 - 3)

21) 7*(x+ 2) = (7*x) + (7*2)

                  = 7x + 14
