Hello!
So, here you want to do the distributive property.
Start on the left side of the + sign...
-3*u = -3u
-3*3 = -9
So we now we have:
(-3u + -9) + 4(4u + 2)
Now we focus on the right side of the + sign...
4*4u=16u
4*2=8
So now we have:
(-3u + -9) + (16u + 8)
Now you want to combine like terms. Start by adding terms with the same variable. So, we need to add -3u and 16u
<em>-3u + 16u =</em> 13u
Now we have:
13u + -9 + 8
Now add the constants, -9 + 8
-9 + 8 = -1
So, the simplified expression would be:
13u - 1 or 13u + -1
They can conclude that the certain animal ( of the fossil) had either migrated to that place or was brought to that certain place this is also proof of of the Continental Drift Theory that there was a Pangaea and split apart around a certain time.
I would be almost certain that it must be racial 16, though I have no idea what that means.
Circle equation: (x + h)² + (y - k)² = r²
The center can be found by looking at (h, k) in the equation.
We are given the equation (x + 5)² + (y - 8)² = 1
The center is (h, k) so, it is (-5, 8)
Best of Luck!
