Select the correct answer. Which statement is always true? A. A cross section parallel to the base of a right rectangular prism is a square. B. A cross section perpendicular to the base of a right rectangular prism is congruent to the base. C. A cross section parallel to the base of a right rectangular prism is congruent to the base. D. A cross section perpendicular to the base of a right rectangular prism has the same dimensions as the base.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
