Answer:

In order to find equation:
<u>Find slope</u>:



Then find equation using:
y - y1 = m(x -x1) where (x1, y1) are points, m is slope



Assuming the length is y and the width is x
Perimeter = y + y + x + x
= 2y +2x
= 2 (y + x)
if the is 8 and the perimeter is 108
108 = 2 (y +8)
108/2 = y+8
54 = y +8
54 - 8 = y
46 = y
Length = 46 inches
Answer:
15cm^2
Step-by-step explanation:
it is basic math to me.
Number of faces + (Number of vertices - Number of edges) = 2
So plugging in the numbers it would then be
18+(12-30)=2
18-18=2
0=2
Kelvin would be wrong and I disagree with him. (Because ...*plugin work cited above*)
