A,B, and C are interior while D is extorior
Step-by-step explanation: However ABCD are the same because they all mean a number and have their own angles Dis the most common number so its related to ABC. :)Hope this helps
<span>Number of values = 5 (There are 5 values given)
Mean = (82 + 44 + 67 + 52 + 120)/5 = 73
Variance = (1/5) [(82-73)^2 + (44-73)^2 + (67-73)^2 + (52-73)^2 + (120-73)^2] = 721.6
Standard deviation = sqrt (721.6) = 26.86</span>
9 pens and 15 puzzles.....GCF is 3
9/3 = 3 : 15/3 = 5
he can make 3 bags, each containing 3 pens and 5 puzzles
6 soft candies and 18 pencils....GCF = 6
6/6 = 1 : 18/6 = 3
he can make 6 bags, each containing 1 soft candy and 3 pencils
8 chocolate coins and 12 hard candies....GCF = 4
8/4 = 2 : 12/4 = 3
he can make 4 bags, each containing 2 chocolate coins and 3 hard candies
let length = x
width is 7 feet less than length
width = x-7
area = length *width
area = x(x-7)
170=x²-7x
x²-7x-170=0
x²-17x+10x-170=0
x(x-17)+10(x-17)=0
(x-17)(x+10)=0
x=17 or x=-10
since length cannot be negative so x=17
and width =x-7 =17-7=10
length =17 feet and width =10 feet
