I need help does anyone understand ?

Two lines parallel to a third line are parallel to each other. always sometimes or never

Two positive integers are 3 units apart on a number line. their product is 108. which equation can be used to solve for m, the greater integer? m(m – 3) = 108 m(m + 3) = 108 (m + 3)(m – 3) = 108 (m – 12)(m – 9) = 108

Find the number of real number solutions for the equation. x2 + 5x + 7 = 0 0 cannot be determined 1 2
