A pack of baseball cards costs $7. Doug has $47. How many packs of baseball cards can he get?

Use set builder notation to represent the following set: { -3, -2, -1, 0}

Atriangle with all sides of equal length is a/an triangle. a. right b. scalene c. equilateral d. isosceles

What is the explicit formula for this sequence? -7, -4, -1, 2, a.) an = 8 + (b - 1)3 b.) an = -7 + (n - 1)3 c.) an = 3 + (n -1) (-7) d.) an = -7 + (n - )
