Answer:
B
The answer is b im doing a type limit.
Answer:
So we must determine the distance between our two given points and that can be found using the distance formula 
.
Plugging the values into the equation and solve
Therefore, our final answer is that the distance is 16.125 units

Not all square roots are irrational. This can be proven by finding the perfect square roots. The sqrt. of 16, 25, and 26, for example, the answers are all rational numbers.
I hope this is what you are asking for; let me know if you need anythings else :)
If these are sides of a triangle apply the Pythagorean Theorem
15^2= 12^2+ BE^2
225= 144 + BE ^2
81= BE^2
9= BE
Hope this helps
Remark
The equation is job1/ time + job2/time = job3/time
Discussion
job one is the time it takes one of the workers to complete the job.
job two is the time it takes the other workers to complete the job
job three is the time it takes to do the job together.
Givens.
Let Marcus's time = m
Let Tony's time be =t
Let their together time = t1
Equation Substitution and solution.
1/m + 1/t = 1/t1
1/6 + 1/4 = 1/t1 The common denominator on the left is 12.
2/12 + 3/12 = 1 / t1
5/12 = 1/t1 Cross multiply.
5*t1 = 12 Divide by 5
t1 = 12/5
t1 = 2 2/5
t1 = 2.4 hours
Cost
1 hour = 43 dollars for labor.
2.4 hours = x dollars for labor.
1*x = 43 * 2.4
x = 103.2 dollars. <<<<< Answer
