Answer:
<u>D) (f o g)(x) = 10x² - 60x + 93</u>
Step-by-step explanation:
f(x) = 10x² + 3
g(x) = x - 3
⇒ (f o g)(x)
⇒ f(x - 3)
⇒ f(x - 3) = 10(x - 3)² + 3
⇒ f(x - 3) = 10(x² - 6x + 9) + 3
⇒ f(x - 3) = 10x² - 60x + 90 + 3
⇒ <u>(f o g)(x) = 10x² - 60x + 93</u>

If it not the answer you can correct me
I’ll need to see the table and I’ll be able to help
-8x+4=36
-4 -4
-8x=32
divde be -8 on both sides
x=-4
Depending on what they want the answer could be 220km in 2hrs. or 110km in 1hr.
