Answer:
2 OR4 ; both correct
Explanation:
x^2=7
x^4+y^2=50
x^4=(x^2)^2=(7)^2=49 --> 49+y^2=50
y^2=50-49=1 --> y=±
--> y=±1
+1 or -1 both possible --> solve both
+1+w=3 --> w = 3 - 1 = 2
OR
-1+w=3 --> w = 3 + 1 = 4
Answer:
0
Explanation:
3 angles in a triangles add up to be 180 degrees (always)
With measures of 120,40 and 10, the angles only add up to 170.
Hence, it's impossible to create a triangle with these measures.

The correct answer is D. Have other scientists repeat the procedure and obtain the same results.
Explanation:
One of the most accurate ways to validate the results of an experiment is to allow peers (other scientists) to review the experiment and repeat it, which is known as replication. This process is required to make sure the results are accurate because if the experiment is repeated by a different scientist and the results are different this shows the data is not consistent and therefore the results are invalid. Moreover, inconsistency or lack of replication can occur due to incorrect processes or bias by the scientist.
According to this, the next step in this situation is to "have other scientists repeat the procedure and obtain the same results".On the other hand, repeating the experiment but changing one of the variables or the procedures is not a correct step because this will change the essence of the experiment and lead to different results.
