In a sequence of numbers, a1 = 3, a2 = 9, a3 = 27, a4 = 81 , and a5 = 243 . Based on this information, which equation can be used to find the nth term in the sequence, an?

The width of a rectangle is 20 units. can the perimeter p of the rectangle be 64 units when its length x is 11 units? no, because p = 2x + 2(20) no, because p ≠ 2x + 2(20) yes, because p ≠ 2x + 2(20) yes, because p = 2x + 2(20)

Solve the equation by completing the square. x^2+2x=17
