For the first question break it down to 2 rectangles and add the areas
14 * 4
and (12-4) * 8 = 8* 8
secon q:-
The other rectangle which has area of 72 is the third choice. Its perimmeter = 2(24) + 2(8) = 64
Positive value of x for the given function 2h(x) = log₂(x² +2) is equal to √62.
As given in the question,
Function h is given by : 2h(x) = log₂(x² +2)
Using the definition of logarithm function
aˣ = y
⇒x= logₐy
For h(x) =3, Apply definition of logarithm function we get,
2× 3 = log₂(x² +2)
⇒6= log₂(x² +2)
⇒2⁶ = x² +2
⇒x² = 64-2
⇒x²= 62
⇒x = √62
Therefore, positive value of x for the given function 2h(x) = log₂(x² +2) is equal to √62.
