Hello plz help
(pls like fr show me how you got your answer and tyy!

We've been given to find out the value for the given algebraic expression which is,

The most easiest way to solve this kind of problem is to find factors for (x² - 16) and cancelling them with the factor of (x + 4) in denominator. The factors for (x² - 16) are (x + 4) and (x - 4). For cross check,

These are correct factors which obeys our expression now as per our question,

Cancelling (x + 4) from both numerator and denominator we get answer as,

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
