So you would set this problem up as 10 x 9 x 8 x 7, since none of the digits can be repeated. There are 5,040 4 digit passcodes possible.
Answer:
Step-by-step explanation:
The question is to factorize 
<em>What is common from all 3 terms?</em> It is the factor 4, so we take out 4 and write the remaining as "factorized form".
(Work shown below):
<u>First answer choice is right.</u>
Yes. Take for example a square and an ellipsis with the same perimeter. The family of ellipses with the same perimeter can have any area between that of a circle to zero (if it is extremely “thin” i.e. if its eccentricity is large). The circle has the maximum area of any other shape with the same perimeter, so the square has the same area of one of the intermediate ellipses.
Answer:
C
Step-by-step explanation:
I could not remeber since it is the next day, since exams sorry :/
replace the numbers given for x & y so
the equation becomes 3*(-3) + 2*(-4) =
3*-3 = -9
2*-4 = -8
-9 + -8 = -17
