Answer:
2 because it holds the same value as -2 and its the additive inverse
You can factor out a 5n to get
5n(4m-3)
Y=11 x=13
It’s a rectangle so each angle equals 90
1
Angle 1 + angle 2 =90
5y+2y+13=90
7y=77
y=11
Th diagnose of a rectangle bisect so 8x-16=5x+23
3x=39
X=13
1 400 000 000 000 000 000 000 km = 1.4 * 10^21 km
Common denominator = 40
36/40 + 20/40 = 56/40
Reduce and simplify=
7/5, which is 1 and 2/5
Hope that helps
