Which equation is an identity? 3(x – 1) = x + 2(x + 1) + 1 x – 4(x + 1) = –3(x + 1) + 1 2x + 3 = 1/2 (4x + 2) + 2 1/3 (6x – 3) = 3(x + 1) – x – 2

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.
