Last problem of the day hopefully I can get all A

Answer:

The answer is 21

Step-by-step explanation:

Simplify  2²  to 4

Simplify 5² to 25

25=b²+4

b²=25-4

b²=21

and because you cant square root 21 the answer would be ±[tex]\sqrt{21}[/tex]

Answer:

squarerot of 21

suareroot of 21 5^2=2^2+b^2 25=4+b^2 21=b^2 squareroot of 21

suareroot of 21. 5^2=2^2+b^2, 25=4+b^2, 21=b^2, squareroot of 21
