B I’m not 100% sure but I think
Answer: 30 kilograms
explanation: Each 1000 grams converts to 1 kilogram
Answer:
C
Step-by-step explanation:
The area of a circle is pi * r^2. The radius is 7 because the diameter is 14 so the radius is 14/2. The square of 7 is 49. Pi is approximately 3.14, so 49 * 3.14 is about 154.
So since its a right triangle, we can use the pythagorean theorem, which is 
. Since we know that 2 and 3 are our legs and x is our hypotenuse, we can solve the equation as such:
Since √13 can't be further simplified, that is your final answer.
the answer is b because the answer for both of them is -39. you might also want to look into the sign rules in algebra bb :)
