Answer:
4√5
Step-by-step explanation:
2√5 + 3√5 - √5 = 4√5
add up 2 and 3 that's in front of √5 then subtract 1 from it
Genotype is the genetic composition of an organism. Alleles are the alternative forms of a gene, they can either be dominant alleles (masks the other allele) or recessive alleles (masked by the dominant allele when present). Autosomal dominant and the autosomal recessive are the most common inheritance patterns.
Answer:
Option 4 is correct. The length of PR is 6.4 units.
Step-by-step explanation:
From the given figure it is noticed that the triangle PQR and triangle MQR.
Let the length of PR be x.
Pythagoras formula

Use pythagoras formula for triangle PQM.





The value of PM is 10. The length of PR is x, so the length of MR is (10-x).
Use pythagoras formula for triangle PQR.


.....(1)
Use pythagoras formula for triangle MQR.



.... (2)
From equation (1) and (2) we get




Therefore length of PR is 6.4 units and option 4 is correct.
