The scale factor that was used to create triangle J’K’L’ is 1/3
<h3>How to determine the scale factor?</h3>
From the graph, we have the following highlights:
KL = 3
K'L' = 1
The scale factor (k) from JKL to J'K'L is calculated as:
Scale factor = K'L'/KL
This gives
k = 1/3
Hence, the scale factor that was used to create triangle J’K’L’ is 1/3

Step-by-step explanation:

Sorry I know this late, but the answer is 40 MPH, I don't know if this helps! I HOPE SO THO!! <3
The expression can be solved by expanding the bracket and multiplying out the terms


Therefore, the expression can be simplified as;

Alternatively, using the theorem of difference of two squares, which is

Hence,

I am quite sure that it is B: Temperature
