Hey there :)
27x² is what we are trying to factorise
When factorising, we do not add but we multiply
Jude factored : ( 20x )( 7x ) → This is wrong, since 20x × 7x = 140x²
Yasmin factored : ( 9 )( 3x² ) → This is right indeed as 9 × 3x² = 27x²
Yasmin is right
If you would like a list of the steps/formula, message me and I'll send it to you as it's too long to post here. The answer to your question would be <span>a21 = 162.
Hope this helped, and if it did I'd appreciate if you marked me as brainliest as I need it to get to a higher rank. If you need any more help, feel free to add me and/or message me :)

Answer:
A; 8.60
Step-by-step explanation:
8.60 = c
If the 1st differences of consecutive y-values are constant or very nearly constant then a linear model will probably fit well. If the ratios of consecutive y-values are constant or very nearly constant then an exponential model will likely work well.
