Step-by-step explanation:
Explaining- when you look at the vertex to the other vertex you see the length and that is when you multiply
Answer- A
4x^2+12x+7x
4x^2+19x
Was it meant to equal something or are you just simplifying the equation?
This is how I solved it.
2.5 multiplied by 3 is 7.5, which equals how many she takes a day.
Then I multiplied 7.5 by 10 = 75. I did that because the meds are taken for 10 days.
Also if you added 7.5 ten times is also 75.
So my final answer is that 75 tablets have been taken in total.
