Hi I don’t know if this is right but I got that k is equal to 4 I got that because if you do
4 times 3/4 you get 12/4 that is equal to 3.
Now you have k + 3=7 you move 3 to the other side and make it negative
K= 7-3
K=4
Hope this helped!
We know that the lengths of the two smaller sides have to be more than the third side when they are added together
The third side couldn't be 2 or 3 because 9 (7+2) or 10 (7+3) are not less than 10
The third side couldn't be 17 or 18 because 17 (7+10) is not larger than 17 or 18
The correct answer is C. 4 works because 7+4=11 or more than 10. 16 works because 7+10=17 is more than 16
Hope this helps

Answer: 50,001²-49,999²=0,2.
Step-by-step explanation:
![50,001^2-49,999^2=(50,001+49,999)*(50,001-49,999)=100*0,002=0,2.](https://tex.z-dn.net/?f=50%2C001%5E2-49%2C999%5E2%3D%2850%2C001%2B49%2C999%29%2A%2850%2C001-49%2C999%29%3D100%2A0%2C002%3D0%2C2.)
