10+9x70
The distributive property is not used in evaluating 49 + 9.
19*70 = (20 - 1)*70 = 20*70 - 1*70 = 1400 - 70 = 1330
8 x 71 = (8 x 70) + (8 x 1)
5(3+9) = 5x3 + 5x9 hope this helps
19*70 = (20 - 1)*70 = 20*70 - 1*70 = 1400 - 70 = 1330. Some may suggest 19*70 = (10 + 9)*70 = 10*70 + 9*70 = 700 + 630 = 1330, but that is much more complicated.
This is the chemical reactivity.
Tinsile strength
Propety abuse???
19
because the solubility is a propety of a substance and some substance will dissolve in some substasnce but no others
distributive
