C. because x represents "a number" it reads, "the difference..." and difference means subtracting. Also how would you write twice a number? 2n, it basically means a number times two. But that's not all. You still have to subtract by 3 so its 2n-3.

A triangle has one angel that measures 51 degrees and one angle that measures 39 degrees. what kind of triangle is it?

sp2606 [1]

Those two angles are complementary - which means they both give us 90 degrees. We know that all three angles in any triangle must be exactly 180 degrees, so the third angle will be 180 - 90 = 90 degrees. It means that our triangle is a <u>straight triangle</u>. The figure will look more less like in the attachment.
