Select true or false for each statement. for a real number a, a + 0 = a. for a real number a, a + (-a) = 1. for a real numbers a and b, | a - b | = | b - a |. for real numbers a, b, and c, a + (b ? c) = (a + b)(a + c). for rational numbers a and b when b ? 0, is always a rational number.

Haruka hiked several kilometers in the morning. she hiked only 66 kilometers in the afternoon, which was 25% less than she had hiked in the morning. how many kilometers did haruka hike in all?

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.
