Answer:
7 inches
Step-by-step explanation:
The area of a square is given by the formula ...
A = s² . . . . . s = side length
Using the given area, you have ...
49 in² = s² . . . . . fill in given value of area
7 in = s . . . . . . . take the positive square root of both sides
The length of a side of the square is 7 inches.
The answer is c. 2 hours and 45 minutes
Let F(x) = x^2 + 2x -8
Adding 1 and - 1 at equation
F(x) = x^2 + 2x + 1 - 1 -8
Rewrinting the first 1 = 1^2
F(x) = x^2 + 2x + 1^2 - 1 - 8
Now look:
x^2 + 2x + 1^2 = ( x + 1)^2
Then,
F(x) = (x + 1)^2 -1 -8
F(x) = (x + 1)^2 -9
This is the answer !
If us to want.
(x + 1)^2 -9 = ( x+1)^2 - 3^2
= ( x+ 1 -3).(x +1 +3)
= ( x - 2).(x +4)

Answer:
the set of all possible input values for a function is called the domain of the function, and the set of all output values for a function is called the range. ... The y variable is the dependent variable and represents the corresponding output value f (x) in the rang
