Answer:
The answer is -a^2 + 3a +1
Let me know if it's right, this is what I got when I did the problem :)
Answer:
13. ABCD and DCBA
14. BA and CD
15. AB abd BC
16. The points B and L can be collinear.
Step-by-step explanation:
See the given diagram of a straight line that extends from -∞ to +∞.
13. ABCD and DCBA are the two different names of the line.
14. BA and CD are the names of different opposite rays.
15. AB and BC are the two line segments.
16. The line between points B and L can be drawn separately. So, the points B and L can be collinear. (Answer)
A square with 1,536 soldiers are not possible, i.e. the square root of 1,536 is about 39.191, which means that 1,536 is not a square a number. In order for it to be a square number, we have to round up 39.191 (because it says "how many more soldiers") to 40 and 40×40=1,600 and 1,600-1,536, so we need 64 more soldiers.
The greatest 4 digit number is simple. If the square root of 10,000 is 100, than, one can assume that because 100-1=99, the resulting answer of 99×99 is less than 10,000, meaning that is is 4 digits. 99×99=9,801.
Answer is x is less than 4
