Tanya likes to take walks around the pentagonal garden at her local park. The garden on the left has congruent sides. If Tanya starts at one vertex of the pentagon and walks all the way around the garden, how far has she walked in total?

The surface area of a rectangular prism is found using the formula SA = 2 (lw + lh + wh), where l is length, w is width, and h is height. What is the surface area (in square meters) of a rectangular prism with length 5 m, width 12 m, and height 6 m?.

If you are given the graph of h (x) = log Subscript 6 Baseline x, how could you graph m (x) = log Subscript 6 Baseline (x + 3) ?
