Let length of  the hypotenuse = 3x and length of given leg be x feet.

then (3x)^2 = x^2 + 648
8x^2 = 648
x^2 = 81


so x = 9 and 3x = 27

Hypotenuse is 27 feet and the leg equals 9 feet.

Mary month earnings can be given as R(x)=13x+155 where x equals the number of hours worked josies monthly are given as Q(x)=9x+3
tatuchka [14]

Answer:

45hours

Step-by-step explanation:

Given

Mary month earnings to be R(x)=13x+155

Josies monthly earning is given as Q(x)=9x+335

If Josie and Mary work to earn the same salary, then R(x) = Q(x)

13x+155 = 9x+335

subtract 155 from both sides

13x+155-155 = 9x+335-155

13x = 9x+180

subtract 9x from both sides

13x-9x = 9x+180-9x

4x = 180

x = 180/4

x = 45

Since  x equals the number of hours worked by Josie and Mary, this means that Josie and Mary must work for 45hours to earn the same salary
