Answer:
find the square of both numbers
13²=169
5²=25
minus the square
169-25 to get 144
find the square root of 144
✓144=12 the third side is 12
The common difference is B. 5 because the numbers are increasing by 5.
By solving a linear equation, we will see that Victor is 30 years old.
<h3>
How old is Victor now?</h3>
Let's say that Victor is x years old.
We know that 10 years ago, (x - 10), his age was half of what it will be in 10 years (x + 10).
Then we can write the linear equation:
(x - 10) = (x + 10)/2
Now we can solve that equation for x:
2*(x - 10) = x + 10
2x - 20 = x + 10
2x - x = 10 + 20
x = 30
So we conclude that Victor is 30 years old.

Answer:
B and D
Step-by-step explanation:
The g(x) = 725 makes no sense to me....
however g(x) = -2x/(x-3) can be solved by plugging x = value into function
a) g(x) = -2x/(x-3)
g(0) = -2(0)/(0-3) = -3
= 0/-3 = 0 ≠ -3 FALSE
b) g(x) = -2x/(x-3) = 1
g(1) = -2(1)/(1-3) = 1
= -2 / -2 = 1 equals 1 TRUE
c) g(x) = -2x/(x-3)
g(2) = -2(2)/(2-3) < g(4) = -2(4)/(4-3)
= -4 / -1 < -8 / 1
= 4 is greater than - 8 FALSE
d) g(x) = -2x/(x-3) both values were already calcuated
g(1) = -2(1)/(1-3) = 1 < g(2) = -2(2)/(2-3) = 4
1 < 4 TRUE
