The are is A=W*L
The perimeter is P=2L+2W
So there is some form of relationship.
A/W=L and P-2W=2L
A/W=L and (P-2W)/2=L
A/W=(P-2W)/2
2A/W=P-2W
2A=PW-2W^2
If you line them up according to the quadratic formula you can have
2W^2-PW+2A=0 where W is the variable equivalent to X in normal circumstances and P and A are set values. There is always a relationship between two numbers, or at least you can almost always create your own relationship. This may seem rather complicated but this is a complicated question and I applaud you for asking something of this sort.
It would be C.
In the second triangle if you add the angles 58+33 to angle C 88, you get 179, not 180. So the triangle dont share the same angles meaning they arent congruent.
Answer:
4x+2
and 22
Step-by-step explanation:
2x-5+6+2x-5+6=4x+2
if x=5, so perimeter 4(5)+2=20+2=22
First u need to divide 135 by 0.4 which equals 337.5, So her gross pay is $337.50
Answer:
[ 1,532.41, 1,617.59]
Step-by-step explanation:
Data provided :
Sample size, n = 120
Mean = $1,575
Standard deviation = $215
Confidence level = 97%
Now,
Confidence interval = Mean ± 
also,
for 97% confidence level z score = 2.17 [from standard z-table]
= $1,575 ± 
= $1,575 ± 42.59
Therefore,
Confidence interval = [ $1,575 - 42.59, $1,575 + 42.59]
= [ 1,532.41, 1,617.59]
