LUCKY_DIMON [66]

Answer:

79 soldiers

Step-by-step explanation:

Since 40 soldiers were not included in the square, the square consists of 6241 soldiers.  6241 represents the area of the square, and the rows (r) represents a side of the square.   Since the area of a square = the length of the side squared, then 6241 = r^{2}.  

So r = \sqrt{6241}

r = 79

Part 2 of 3
dlinn [17]

Considering that point S splits segment RT, we have that:

a) The value of y is of y = 4.

b) The lengths are: RS = 29, ST = 19.

<h3>How to find the value of variable y?</h3>

Point S splits segment RT into two parts, hence the length of segment RT can be given by the following equation:

RT = RS + ST

The measures are given as follows:

  • RS = 6y + 5.
  • ST = 3y + 7.
  • RT = 48.

Hence we can solve the equation for y, as follows:

RT = RS + ST

6y + 5 + 3y + 7 = 48.

9y = 36.

y = 4.

<h3>What are the lengths of segments RS and ST?</h3>

Considering that y = 4, we have that:

  • RS = 6y + 5 = 6(4) + 5 = 29.
  • ST = 3y + 7 = 3(4) + 7 = 19.
