The product of two consecutive integers is 72. The equation x(x + 1) = 72 represents the situation, where x represents
the smaller integer. Which equation can be factored and solved for the smaller integer?
O x²+x-72=0
O x2 + x + 72 = 0
x²+2x - 72=0
O x2 + 2x + 72 = 0

Which of these statements is correct? the system of linear equations 6x - 5y = 8 and 12x - 10y = 16 has no solution. the system of linear equations 7x + 2y = 6 and 14x + 4y = 16 has an infinite number of solutions. the system of linear equations 8x - 3y = 10 and 16x - 6y = 22 has no solution. the system of linear equations 9x + 6y = 14 and 18x + 12y = 26 has an infinite number of solutions.
