Let us assume for starters that it is true.
The area of the square is s^2, so that is where you start.
(1 + 2*sqrt(2) ) ^2 = 1 + 4*sqrt(2) + 8 Taking 1 away form that does not leave you with 8.
Let's start again.
If all sides are reduced by 1 , but the square is retained, then the length of the side is 2sqrt(2). Now we have
s^2 = (2sqrt(2) )^2 = 4 * 2 = 8
The question is really not worded clearly enough to give an answer. I think it's true, but the language has to be twisted a bit.
Answer: I'd answer true, but don't be surprised if it is not interpreted the way I did on my second try.
the answer is <em>56</em>
<em>explanation:</em>
to double something you have to multiply (or divide) by 2. if the total amount of bagels sold on friday was 112, you divide 112 by 2, and get 56.
—625 because you would multiply -5 four times
Answer: 60
Step-by-step explanation: To find 50% of 120, first write 50% as a decimal by moving the decimal point two places to the left to get .50.
Next, the word <em>of</em> means multiply, so we have (.50)(120) which is 60.
This means that 50% of 120 is 60.
