Answer:
2
Step-by-step explanation:
1st step: solve the exponential number
2x^2=4x
3x^2=9x
2nd step: rewrite the number sentence with the exponent solved
4x-8x+8 9x+27x-30
3rd step : solve
4x-8x=-4x 9x+27x=36x
-4x+8= 36x-30=
4 6
Step 4: See what least common multiples they have in common
4 LCM =2 * 2= 4 6 LCM= 2*3=6
So the LCM is 2
Answer:
The answers is "
Option B".
Step-by-step explanation:

Where,
predicted value of lead content when traffic flow is 15.


Calculating thet-critical value
The lower predicted value 

When
of CI use as the expected lead content:

Multiply:
6•12=72
Then, you subtract 39 from 72:
72-39=33
33 containers would still need to be set up.
58 103 72
47 13 71
