By the binomial theorem, the 
term in the expansion of 
is
which suggests that the contribution of the binomial coefficient should make up the remaining factor of 21. That is,
Answer: 86
Step-by-step explanation: 96 is 105 we need find 100% so we need to find per percent
Hello :
4√2-7√2= (4-7)√2 = -3√2
The <em><u>correct answer</u></em> is:
$43.20
Explanation:
The formula we have is
c = p(1+r), where c is the total cost, p is the price of the item before tax, and r is the tax rate written as a decimal. This formula comes from the fact that adding a percent tax to the cost of an item takes 100% of the price and adds r% to it; this is why we multiply the price by (1+r).
Since our tax rate is 8%, r = 8% = 8/100 = 0.08. The price of the item is $40. Using this information, we have:
c = 40(1.08) = $43.20
