Was this a fair test? is it representative of the effectiveness of the test substance

1 answer:

8 0

<span>No. The test is not a fair test. The test is artificial. Testing the disinfectant against bacteria in a test tube is not representative of the effectiveness of the disinfectant against microbes in the environment. Test tube tests test for efficacy. Effectiveness can only be tested out in the environment.</span>

LMNP is a rectangle. Find the value of x and the length of each diagonal. LN= x and MP= 2x -8

loris [4]

Answer:

<h2>x = 8 (Verified) ✅</h2>

Step-by-step explanation:

If we visualize the figure, we can see that sides LN and MP are going to be parallel and of the same length.

So x = 2x - 8

Subtract x

0 = x - 8

x = 8

Check the answer

8 = 2(8) - 8

8 = 16 - 8

8 = 8 ✅
