\pi {r}^{2}

each square has an area of 1

the area of the 5 squares plus the area of the two circles equals the total area.

aleksley [76]

Answer:

14

Step-by-step explanation:

Let's find (f-g)(x)

3x^{2} + 1 - (1-x)\\3x^{2} + 1 -1 + x\\3x^{2} + x

Now let's plug in x=2, so to find (f-g)(2)

3(2)^{2} + 2\\12 + 2 = 14

The mean of 4 numbers is 15. 3 of the numbers are 18, 14 and 12. What is the other number?
Kisachek [45]

Answer:

Call the numbers a, b, c, d. What does it say if their mean is 15? That would be that added together then divided by 4 you get 15. So the number before you divided by 4, which is the sum, was 60. If you know some algebra, the equation (a+b+c+d)/4=15 gives the sum of 60 when you multiply both sides
