Answer:
5
Step-by-step explanation:
A^2 +B^2 =C^2
12^2 + b^2 =13^2
144+ b^2 =169
= 25
x=5
Is there a picture or text?
The answer is 4 because 1 6/8 + 2 3/8 =4 1/8 so it would round to 4
Answer:
Since the value of f(0) is negative and the value of f(1) is positive, then there is at least one value of x between 0 and 1 for which f(x) =0.
Step-by-step explanation:
The equation f(x) given is:

For x = 0. the value of the expression is:

For x = 1, the value of the expression is:

Since the value of f(0) is negative and the value of f(1) is positive, then there is at least one value of x between 0 and 1 for which f(x) =0.
In other words, there is at least one solution for the equation between x=0 and x=1.
Both A and C are used within this problem. Distributing happens in the first and second step. Also, Inverse operations are used in nearly every step that is solving.
