It’s B
You need to use the Pythagorean theorem which is a squared + b squared = c squared
So a^2+4^2=5^2
Simplified that would be a^2 + 16 = 25
Subtract 16 from both sides
A^2=9
And the square root of nine is 3
“Same signs add and keep”
Negative minus negative you add them and keep the negative sign
-1 12/12
12/12= 1
=-2
Or make it into an improper fraction -1 5/12 is also -17/12
17+7= 24
-24/12 = -2
Let
be the average salary of an employee. Since the salary of the business man is 6 times the average salary of an employee, his salary will be
