Estimate 189 to the nearest tenth which would be 190. And then do the same for 643 which would be 640. 640-190= 450
Answer:
4
Step-by-step explanation:
The area is 16, and you know that it's 2 sides u need to multiply
The perimeter is 16, and you know that you need to add up all the sides
So....
A = b * h
A = 4 * 4
A = 16 CORRECT
And....
P = S + S + S + S ( s = sides)
P = 4 + 4 + 4 + 4
P = 16 CORRECT
Hope this helped!

B(5 - 2, -6 + 3, -1 + 1) = B(3, -3, 0)
Tell me if you're still confused.
3x + 6 = 12
First operation was subtraction (subtracting 6 to leave 3x alone)
Second operation was division (Dividing 3 from 3x to isolare x)
3x + 6 = 12
3x + 6 -(6) = 12 - 6
3x = 6

=

3 and 3 cancels out
x = 2
