Answer:
This proof can be done by contradiction.
Let us assume that 2 - √2 is rational number.
So, by the definition of rational number, we can write it as
where a & b are any integer.
⇒ 
Since, a and b are integers 
is also rational.
and therefore √2 is rational number.
This contradicts the fact that √2 is irrational number.
Hence our assumption that 2 - √2 is rational number is false.
Therefore, 2 - √2 is irrational number.
Answer:
A
Step-by-step explanation
You can divide 6x,9y and -15 by 3
6x/3=2x
9y/3=3y
-15/3=(-5)
Combine them to get the factored form of 6x+9y-15:
3(2x+3y-5)
32-3 which is 29 Im pretty sure
Answer:
32.4kg
Step-by-step explanation:
if it loses one tenth of cement;
36kg×1/10
36kg/10
3.6kg was lost
to find the remaining ; 36kg - 3.6kg = 32.4kg is left in the bag
<span>22% of $40 is $8.80 so the now rate should be $40.00+$8.80=$48.80</span>
