Step-by-step explanation:
(3x+1)(x-3)-(2-2x^2-3x)
3x^2+x-9x-3-2+2x^2+3x
3x^2+2x^2+x-9x+3x-3-2
5x^2-5x-5
the constant term in the simplified expression is -5.

Step-by-step explanation:
we know that
The probability that it will hit a point in the outer (yellow) ring is equal to divide the area of the yellow ring by the total area of the target
step 1
Find the area of the yellow ring
![A=\pi [7^{2} -5^{2}]](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5B7%5E%7B2%7D%20-5%5E%7B2%7D%5D)

step 2
Find the total area of the target
![A=\pi [7^{2}]](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5B7%5E%7B2%7D%5D)

step 3
Find the probability

Convert to percentage

Answer:40
Step-by-step explanation:4 tablets twice a day is 8 (4*2=8). 3 tablets twice a day (3*2=6) for days 2-6 which is 5 days (6*5=30) is 30. The 7th day is 1 tablet twice a day (1*2=2). You’re multiplying the tablets Ben has to take times 2. Add them all together and you have 40.
