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

Use the difference of squares pattern to factor the polynomial.x2 − 16y2 how would I do this
love history [14]
The general rule for difference of two squares is that when factorised it can be written in the form (a+b)(a-b) where a is the square root of the first part of the function and b is the square root of the second part of the function.
From this we can find the square root of x² to find a and the square root of 16y² to find b.
In this case √x²=x and √16y²=4y
Therefore fully factorised it can be written as (x+4y)(x-4y)
