Answer:
2(7.5x+3.5)
Step-by-step explanation:
I can't remember what these equations are actually called, however in order to solve this you simply multiply 7.5 by 2, and then 3.5 by 2.
Maybe put them in order so I could possibly answer
It’s 10 and 12 because it’s 11 but it’s a decimal that goes on longer than 5 times hope this makes sense
It would likely just be written as "two point four five", or "two and forty-five hundredths".
