Answer: Scientific knowledge?
I’m not really sure what you’re asking, but I hope this helped!
Step-by-step explanation:
Let's call the width: w
the lenght is then 3w+4 ("4 more than 3 times the width")
and the parameter would be 2(w+3w+4), that is 2*(4w+4), that is 8w+8.
this is also equal to 18.4:
8w+8=18.4
8w=10.4
w=1.3
this is the width, and the lenght is:
4+3*1,3=4+3.9=7.9
and the area is their product:
1.3*7.9=10.27
The answer is b. the correct thing to say is "<span>If the diagonals of a quadrilateral bisect each other, then the quadrilateral is a Rectangle."</span>
<span><u><em>The correct answers are: </em></u>
B) have the same vertex
C) be congruent.
<u><em>Explanation</em></u><span><u><em>: </em></u>
Vertical angles are defined as opposite angles that <u>share only a vertex</u>. This definition is why B is true.
Since they are opposite angles, that means that the sides of one angle will be opposite the sides of the other; since this is true, the angles must be <u>congruent</u>.</span></span>
