Answer:
3.472
Step-by-step explanation:
The angle of the semtrical cube times the number of 2 because of the number in the area. So the anser is 3.472.
The sum of the left side of these two equations is equal to the same of the right side is these two equations
4x+8y + (-4x+2y) = 20 + 30
10y =50 ( x is eliminated)
y=5
Take this into the second equation
-4x +2y = 30
-4x + 2*5 = 30
x=-5
So x=-5
y=5
It’s D, 10.7
8 - (4.7 x (-1)) - 2 = 10.7
(8+15+8+3+12)/2+1=24th number will be median
So median is gonna be 21
