I am completely lost on this one it’s from algebra nation

The answer to your question is the second and the last choices

Step-by-step explanation:

Data

Enterprises               cost             cost per hour

Rock the house        $500              $50

Elegant home                                  $75

Process

1.- Write an equation for the total cost in Rock the house

         Total cost = $500 + 50h

2.- Write an equation for the total cost in Elegant home

          Total cost = $75h

Solution

- The first option is incorrect because it does not consider the initial cost

- The second option is correct

-The third option is incorrect, it would be correct if they work with both enterprises

-  In rock the house     500 + 50(15) = 500 + 750 = $1250

- In Elegant home        75(15) = $1125

-The last option is also correct

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
