Answer:
4x^2+6x+2
Step-by-step explanation:
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:
x=6
Step-by-step explanation:
2 (x-4) +3 =7
Subtract 3 from each side
2 (x-4) +3-3 =7-3
2(x-4) =4
Divide each side by 2
2(x-4)/2 = 4/2
x-4 = 2
Add 4 to each side
x-4+4 =2+4
x=6
