Basically, you plug in -4 for x and -7 for y (since -4 is the x coordinate and -7 is the y coordinate). When doing that, you get:

-14=-16+2

-8+7=-1

im not gonna say the answer, but looking at these equations, you can probably tell if they work or not :)

Need help fast please thanks

Answer:

c = 41 ft

Step-by-step explanation:

To solve this problem, we can use the pythagorean theorem, which is defined by the formula $a^2+b^2=c^2$ . We are given both the lengths of the legs, so all we need to do is to plug them both in and solve for c:

$9^2+40^2 = c^2\\c^2 = 81 + 1600\\c^2 = 1681\\c = 41$

This is the first option.
