Answer: 11.18
Step-by-step explanation:
You’re substituting 5 for x in the equations...
Sqrt[x^2+4x^2]
Sqrt[5^2+4(5)^2]
Sqrt[25+4(25)]
Sqrt[25+100]
Sqrt[125]
a = 
isolate the term in a
a²bc = d ( multiply both sides by 4 to eliminate the fraction )
a²bc = 4d ( divide both sides by bc )
a² = 
Take the square root of both sides
a = 
7:2
