780 students stand in rows and columns. each row has an equal number of students and each column has an equal number of students

Alex73 [517]

Answer:

Step-by-step explanation:

x = number of rows

780=x(x+4)

$780=x^{2} +4x$

$x^{2} +4x-780=0\\(x+26)(x-30)=0\\x=30 \\x\neq -26\\$

there are 26 rows and 30 students in each row 26*30=780
