A bricklayer is building a large base for a sign. She uses 6 blocks for the top layer and each layer requires 8 more blocks than the layer above it. The bottom layer has 102 bricks. How many layers are there in the sign base? Describe an equation-based method to answer the bricklayer question.

Describe a pictorial- or manipulative-based method to answer the bricklayer question.

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.
