Answer:

x=3

Step-by-step explanation:

  1. subtract 2x and 9x ( 2x-9x= -7x)
  2. subtract 17 and -4 ( -4 -17= -21)
  3. divide -21 and -7 ( -21 / -7= -3)
  4. x=3

Answer: x = 3

Step-by-step explanation: Simplify both sides

2x - 9x + 17 = -4

2x + - 9x + 17 = -4

Combine like terms

(2x + -9x) (17) = -4

-7x + 17 = -4

Subtract 17 from both sides

-7x + 17 - 17 = -4 - 17

-7x = -21

Divide both sides by -7

-7x/-7 = -21/-7

x = 3

What is the length of the hypotenuse? If necessary, round to the nearest tenth.
artcher [175]

Answer:

17 kilometers

Step-by-step explanation:

The pythagorean theorm is a^2 + b^2 = c^2

In this problem we can call 8 km a and 15 km b.

Plug 8 and 15 into the pythagorean theorm to get 8^2 + 15^2 = c^2

This will give you 289=c^2

Take the square root of both sides to get c=17

Hope this helps!
