Hello!
As you can see, two of the triangles that we see that are made from the lengths we are given make up one face of the pyramid. We can use the triangle formula without multiplying by 1/2 to find the length of one face.
30(45)=1350
Now we multiply this by four to find all of the sides.
1350(4)=5400
We find the area of the square base
30(30)=900
Finally, we add up our lengths.
5400+900=6300
Therefore, our answer is C) 6400 yards²
I hope this helps!

Of the isometries, translation is your best tool. The orientation is already correct so rotation is unnecessary, as is reflection.
Answer:
x=-15.2
Step-by-step explanation:
Answer:
A (-5,2)
Step-by-step explanation:
5x+y=-23
7x-3y=-41
3×(5x+y)=3×(-23)
15x+3y=-69
<u>+</u><u>7x-3y</u><u>=</u><u>-41</u>
<u>22x</u>=<u>-110</u>
22. 22
x=-5
5x+y=-23
5(-5)+y=-23
-25+y=-23
<u>+25</u><u>.</u> <u>+25</u>
y=2
When using elimination you add both equations together so that one variable cancels out the other. In this situation, y can be the variable. You must get the y-variables to cancel out leaving just the x- variables to solve for.
