Answer:
it is
Step-by-step explanation:
We have the next inequation
8-4x<56
-4x<56-8
-4x<48
-x<48/4
-x<12
x>-12
Solution: x>-12 or (-12,+∞)
We apply the mid point formula
That is for two points
The mid point is given by
So we plug the values
So we can simplify it now factor 2 on both
We get
we can cancel out the 2 in numerator and denominator
So
Final answer is Option D
(m+p),(n+r)
3 x 3 x 3 = 27
Each of the 3 layers has 3 x 3 cubes
All minute cubes on bottom layer touch bottom of box
All minuscule cubes (except for middle cubes) of middle and top layers, touch sides of box
So 2 cubes don't physically contact bottom or side of box
Answer: 25
