Final answer:
Brenda is accurate in determining the equivalent ratios concerning Karima's ratios and columns 2 and 4.
Step-by-step explanation:
The accurate person in determining the equivalent ratios is option B) Brenda only, concerning Karima's ratios and columns 2 and 4.
Brenda's statement is supported by the fact that the mathematical expression X = Y x 2 + 1 represents the general proportions of the building. This means that the number of columns used along the length of the temple (Y) is twice the number plus one the number of columns across the front (X). Therefore, Brenda's understanding of the ratios between columns 2 and 4 is accurate.
In contrast, Karima's ratios regarding columns 4 and 8 (option A) and Xavier's consideration of Karima's and Brenda's ratios in columns 1 and 2 (option C) are not supported by the given information. Jody's assertion that any pair of columns with even numbers forms equivalent ratios for 4:8 (option D) is not accurate because the given information does not mention the specific ratio of 4:8.
