Question

(ii) 9X(-13) +9x(-7)
(iv) (-16) (-15) +(-16)x(-5)
(vi) 10x(-12)+5x(-12)
(viii) (-26) x 72 +(-26) x 28
(ii) (18) x
1 =(-18)​

Answer 1

Answer:

(ii) 9X(-13) +9x(-7)= -180

(iv) (-16) (-15) +(-16)x(-5)= 320

(vi) 10x(-12)+5x(-12)= -180

(viii) (-26) x 72 +(-26) x 28= -2600

(ii) (18) x = 18x

1 =(-18)​ = 18=-1
