2(x + 4) = -5x + 1
2x + 8 = -5x + 1
2x + 5x = 1 - 8 = -7
7x = -7
x = -7/7 = -1
x = -1
The answer is 10 to the 2nd power
They are composed of only two atoms of the same or different chemical elements.
Answer: Horse at Z (1640.1m from barn)
To answer this question you need to determine each horse distance to their barn. For horse H the distance would be
X: 1-(-3)= 4
Y: 10-(-9)= 19
If you use <span>Pythagoras theory then the distance would be
</span>BH^2= 4^2 + 19^2
BH^2= 377
BH= 19.416
Horse H is 1941.6m from the barn
For horse Z the distance would be:
X: 10- (-3)= 13
Y: 1-(-9)= 10
BZ^2 = 13^2 + 10^2
BZ^2 = 269
BZ= 16.401
Horse Z is 1640.1m from barn, a bit closer than horse H
