Answer:
7.07
Step-by-step explanation:
If the square has an area of 25 then its side lengths must be 5 by 5.
The diagonal of the square can be found using the Pythagorean theorem. Substitute a = 5 and b = 5.
5² + 5² = c²
25 + 25 = c²
50 = c²
√50 = c
7.07 =c
To find the inverse of a function, replace every x in the equation with a y, and replace every y in the equation with an x:

Add 9 to both sides:

Square root both sides to get y by itself:

This equation can be simplified by taking the square root of 9 out of the root:


The inverse of this function is
y = 3 + √x.
The answer is 2
-3.8+(-0.6)= -4.4
-4.4+6.4=2
