Answer:
wait whats the question-
Step-by-step explanation:
False, all integers are rational because they can be expressed as a fraction. Like -4 is a rational number because it can be -4/1. All integers are rational.
In parallelograms, opposite sides are congruent, meaning that they are the same lengths. So, we have:
y - 4x = 9
-x + 4 = y
Add x to both sides of the second equation:
y + x = 4
y - 4x = 9
This is a system of linear equations. Solve by eliminating the y and subtracting the two equations:
5x = -5
x = -1
Use x to solve for y:
y + (-1) = 4
y = 5
So, x = -1 and y = 5.

scale factor or the similarity ratio is the ratio of two similar geometric figures of their
corresponding sides, volumes or areas. The scale factor is calculated by locating the
corresponding sides on each figure, calculating the volumes and areas and dividing them.
similarity ratio = 2197 m^3 / 512 m^3 = 4.3</span>
