They are multiplying by two .
Answer:
C) 16, 6
Step-by-step explanation:
- Set AB and DC equal to eachother. 4x = x + 12.
- Subtract x from both sides. 3x = 12
- Divide by 3 to get x alone. x = 4
- Plug this x value in the equation for AB. 4•(4) = 16
- We know the AD equals 6, so that will be one of the values and we now know that AB equals 16.
Answer:
9. 16.34

just look up circumference of a circle and you should be able to put the radius in the first thing that pops up :)
I don't know if i'm right or what because I haven't learned binomial in like almost 4 years. (3x+y)?
3x-4 is the answer, you have to see that if its 3 times her nieces age it would be 3x and if its four less than that it is 3x-4
