Answer:

<h2>x-intercepts:</h2><h2>x = -2 and x = -3 ⇒ (-2, 0) and (-3, 0).</h2>

Step-by-step explanation:

a major arranges his soliders in rows to form a perfect square 40 soliders are left out if the total no. of soliders are 6281, f
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
