Choose the correct simplification of the expression (−2x + 4y)(3x − 7y).
Rudik [331]
-2x • 3x = -6x2 (the 2 is an exponent)
4y • -7y = -28y2 (the 2 is an exponent)
-2x • -7y = 14xy
4y • 3x = 12xy
14xy + 12xy = 26xy

—> -6x2(expo) - 28y2(expo) + 26xy

A ferry is a large ship that carries passengers and loads on water.

A ferry rarely sinks. Infact, the United States experience very low cases of shipwreck yearly. According to wikipedia in 2018, not more than 200 shipwrecks happened all over the world compared to a great number of operations that year.

Therefore, based on statistics, the ferry is unlikely to sink.
