The missing number is 6 because half of 18 is 9 and half of 12 is 6
Could you please explain how to work this app
In order to prove that this quadrilateral is a parallelogram, we need to get the opposite sides to be parallel.
The answer would be D because it shows 2 triangles to be equal. If they are equal then they must have corresponding sides.
One function you would be trying to minimize is
<span>f(x, y, z) = d² = (x - 4)² + y² + (z + 5)² </span>
<span>Your values for x, y, z, and λ would be correct, but </span>
<span>d² = (20/3 - 4)² + (8/3)² + (-7/3 + 5)² </span>
<span>d² = (8/3)² + (8/3)² + (8/3)² </span>
<span>d² = 64/3 </span>
<span>d = 8/sqrt(3) = 8sqrt(3)/3</span>
Answer:
A. 
Step-by-step explanation:
We need to determine whether the polynomial
can be factored into perfect squares. If so, factor the polynomial. Otherwise, select that it cannot be factored into a perfect square.









Hence choice A.
is correct.
