Answer:
fastest in rivers, slowest in groundwater
Explanation:
For rivers, lakes and groundwater, self-purification is fastest in rivers and slowest in groundwater.
When groundwater becomes contaminated, it tends to remain contaminated because the dissolved oxygen levels are low or non-existent.
The answer is National security because the citizens need to know that they are being protected, and usually also how they are being protected. But the government often needs so measure of secrecy in order to protect National Security. If the government were to tell citizens exactly how they were being protected and someone posted it onto the internet it would severely compromise that protection. However people do not generally seem to understand that and tensions become heated between the two groups. Both sides reasons are perfectly legitimate, but one outweighs the other by knowledge. The answer is B.
In each quantity (the area where the parenthesis are), you must distribute the outside number to each term on the inside. -6 multiplied by x is -6x. -6 multiplied by 3 is -18 (always remember that if one factor is negative, then your product is negative. If both factors are negatives, then your product is positive). -(1/4) multiplied by 4x is -1x or -x. -(1/4) multiplied by -8 is 2. Add all your values together. The values with x's may only multiply to other values with x's.
-6x-1x-18+2
Combine the x values(add)
-7x-18+2
Combine regular numbers(add)
-7x-16
This is your final answer.
