Answer:
zero ang sagot :)
Step-by-step explanation:
(0×6)×(3.15-8)×(9-5)
0(3.15-8)×(9-5)
=0
A postulate is a statement in math that is so obvious that it does not need to be proven, that is basically what it means, in layman's terms
The best way to multiply complicated problems mentally* is to break them into chunks.
Start with 20 times 8 to get 160, and then 8 times 5 to get 40. Add these together to get 200. 200 times 3 is 600, and 20 times 200 is 4000. Add these together to get your final answer, 4600.
In other words 8 x 20 + 8 x 5 = 200 200 x 3 + 200 x 20 = 4600
*I assumed you meant mentally, because otherwise you'd just multiply longhand, multiplying two of the three numbers and then multiplying their product with the third.
The answer is 4 because k+2 would be 2 then times by 6 which is 12 then subtract 8 would be 4
