(6 + 3) + 21 = 6 + (3 + 21)
It's an ASSOCIATIVE PROPERTY
(a + b) + c = a + (b + c)
The equivalent fractions are 3/4 & 12/16 hope this helps!!
Answer:
unbounded region
A feasible region that cannot be enclosed in a closed figure is known as an unbounded region. A feasible region is a set of all possible points of an optimization problem that satisfy the problem's constraints; feasible sets may be bounded or unbounded.
Step-by-step explanation:
The absolute value of zero is zero
1/4x+4/4x = -6/2x+1/2x
5/4x = -5/2x
x=0
