Answer:
x = 142
Step-by-step explanation:
The problem;
Inverse operations;
Now undo the square, by squaring both sides;
Inverse oeprations;
x + 2 = 144
-2 -2
x = 142
Assume (a,b) has a minimum element m.
m is in the interval so a < m < b.
a < m
Adding a to both sides,
2a < a + m
Adding m to both sides of the first inequality,
a + m < 2m
So
2a < a+m < 2m
a < (a+m)/2 < m < b
Since the average (a+m)/2 is in the range (a,b) and less than m, that contradicts our assumption that m is the minimum. So we conclude there is no minimum since given any purported minimum we can always compute something smaller in the range.
W + 2w = 60
this equation is wrong

The formula we use is d=c/π.
Answer:
n=13/7
Step-by-step explanation:
2n+4+6*2=-9*2+8(2n+1)
2n+4+12=-18+16n+8
16+18=16n-2n+8
34=14n+8
34-8=14n
26=14n
n=13/7
