Algebra 2 Big Idea Math online assignment for Chapter 5.5 where f(x) = 11x cubed and g(x) = 7x to the 2/3s power and it wants me to find fg and f/g letting x = -8 it also wants me to find the domain of both of these functions and the value of - before making it -8

Given: abcd is a square. prove: ac ? bd. we are given that abcd is a square. if we consider triangle aeb and triangle aed, we see that side is congruent to side ad because sides of a square are congruent. we know that side ae is congruent to side ae by using the . finally, we know that side de is congruent to side because the diagonals of a square bisect each other. therefore, triangle aeb is congruent to triangle aed by congruency. we see that angle aed and angle aeb are a linear pair, and congruent by cpctc. thus, the measure of these angles will be 90°, and diagonal ac is perpendicular to diagonal bd by the .
