Answer:
The numbers are 9, 19 and 76.
Step-by-step explanation:
Let's take the second number and make it a variable, like x. Now let's find all the other numbers in terms of x.
The first number in terms of x:
The second number in terms of x:
If we add them all up, these 3 numbers in terms of x must be equal to 104, so:
Now that we know the second number, we can find the other numbers since we already figured out their values in terms of x:
The first number is 9, second number 19 and the third number 76.
Answer:
Step-by-step explanation:
<span>We can assume the numbers are 161 and 163
it can also be showned by adding and subtracting the numbers by 1.
For example.
Numbers refering to 2; 1 and 3
To solve this equation we can first assume that both a and b are nonzero real numbers. Hence, A = 1 b = 1 </span><span><span>
1. </span>2 (1) + 1 = 3</span> <span><span>
2. </span><span> 2 + 1 = 3:
3. 3 - 1 = 2

<span>Numbers refering to 100; 99 and 101
To solve this equation we can first assume that both a and b are nonzero real numbers. Hence, A = 1 b = 1 </span><span><span>

Answer:
81
Step-by-step explanation:
100 - 19 = 81
and 81 = 9² ← a square number
Answer:
Domain [-4 , +∞)
Range [0 , +∞)
Step-by-step explanation:
the function g such that g(x)=√(x+4) ,is defined
for the values of x that verify :
x + 4 ≥ 0
⇔ x ≥ -4
Then
The domain of g is [-4 , +∞)
………………………………………………
Let x ∈ [-4 , +∞)
then x ≥ -4
then x + 4 ≥ 0
then g(x) = √(x+4) ≥ 0
Therefore, we can affirm that the range of g is [0 , +∞)
