What is the length of the hypotenuse for a right triangle with legs of length 9 and 40?​
Step2247 [10]

Answer:

c = 41

Step-by-step explanation:

{c}^{2}  =  \sqrt{ {a}^{2} +  {b}^{2}  }

c =  \sqrt{ {a}^{2} +  {b}^{2}  }

c =  \sqrt{ {9}^{2} +  {40}^{2}  }

c =  \sqrt{81 + 1600}

c =  \sqrt{1681}

c = 41

Is x = 2 a solution of the equation 8 - 5x = 3?*<br> (5 Points)<br> O Yes<br> O No
kondaur [170]

Answer:

No sir

Step-by-step explanation:

first you will try to get x  by its self.

so were it says  -5x = 3 you wanna do

                          +5    +5 on both sides to cancel out 5 so that would be

                             X =  8  because -5 + 5 is 0 which in this case will be left with X

 you already have 8 so x = 8  

Hopefully this helps
