Answer:
No it's false!
Step-by-step explanation:
8*11=(8*10)+(1*10) = False
8*11 = 88
8*10 = 80 + 1*10 = 10
80+10 = 90
no
8*10=80, 1*10=10
80+10=90
8*11=88
88 does not equal 90 so no
thta is confusing try google
-30x-27y = -21
We know that;
-30x-27y = 3(-10x-9y)
Recall, -10x-9y = -7
Thus; -30x-27y = 3(-7) = -21
The answer is 3:2 look at the explanation
