Answer:
Sum of and is
Option B is correct answer.
Step-by-step explanation:
We need to find sum of and
Finding sum of and :
We know that
Replacing x^2-4
Now, taking LCM of (x+2)(x-2) and (x+2) we get (x+2)(x-2)
So, Sum of and is
Option B is correct answer.
5.48 x 10^4
the decimal place would need to be moved 4 to the right (hence 10^4)
I think the answer is the slope is -2 and the y-intercept is 12
Paula's dog is 36 lbs
Use the equation 48=3x+x
Add like terms: 48=4x
Divide: 12=x (x=Carla's dog's weight)
Then Multiply x by 3 to get Paula's dog's weight and you get 36 lbs
