What is -2m+4n to the second power for m=-6 and n=-5
1 answer:
-2m + 4n
(-2m + 4n)^2
(-2(-6) + 4(-5))^2
12 - 20 = -8^ 2 = 64.
I believe the correct solution would be 64.

Answer:
B
Step-by-step explanation:
pretty sure its b.......
You can use Pythagoras theorem to find the radius.
r^2 + 8^2 = 10^2
r^2 + 64 = 100
r^2 = 36
r = 6
The distance formula is d=\sqrt{(x_{2}, x_{1})^{2} +(y_{2}, y_{1})^2
7=x1
4=y2
-8=x2
4=y2
Just plug in the missing values into the equation and solve the equation :)
