L=7+w
P=(12x+14)=2(6x+7)
l+w= P/2 = 2(6x+7)/2= 6x+7
l+w=6x+7
2l = 6x+7
l = (6x+7)/2
l=7+w
-> w= l-7
= [(6x+7)/2] -7
= (6x+7-14)/2
= (6x-7)/2
1/40 = .025, just multiply this by 21 and you have your answer
.525
Answer:
The answer Is C because after further review I have realized C is the best answer choice
Answer:20p+16
Step-by-step explanation:
Combine like terms
4(7p+4-2p)
4(5p+4)
Distribute
4(5p+4)
20p+16
3, 12, 15, 25, 30, 40The range is the difference between the greatest and smallest values:
range = 40 - 3 = 37
Thee average is the sum of elements divided by the number of elements:
average = (<span>3 + 12 + 15 + 25 + 30 + 40</span>)/6
average = 125/6 = 20.83
