Well, if you need 5 bananas and there’s 10 you only take 5 (subtract) say you need 3 lemons in a recipe but you only have 2. you go to the grocery store and get another one (adding). i don’t know if this is the answer ur look for but hope it helps.
Answer:
length of each edge = (x + 3)
Step-by-step explanation:
The surface area of each face of the cube = (
+ 6x + 9) 
. But the surface of a cube has the shape of a square. So that,
Area of a square = length x length
= 
By factorizing the area,
+ 6x + 9 = + 3x + 3x + 9
= ( + 3x) (3x + 9)
= x(x +3) + 3(x + 3)
= (x + 3)(x + 3)
= 
+ 6x + 9 =
Thus,
=
find the square root of both sides
l = (x + 3)
length of each edge = (x + 3)
Answer:
2.25
Step-by-step explanation:
Put the ages in each list in order from smallest to largest.
Smith: 62, 63, 63, 64, 64, 65, 66, 66, 67, 68
Thompson: 75, 76, 76, 77, 78, 78, 79, 80, 80, 81
Find the mediant (number in the middle of the sorted list). There are 10 numbers in each list, so average the 5th and 6th numbers because they are nearest the middle.
Smith: (64 + 65)/2 = 64.5
Thompson: (78 + 78)/2 = 78
The difference between the medians is 78 - 64.5 = 13.5
The range (the difference between smallest and largest age) is 6 for each of the two lists.
13.5 = (multiplier)(6)
multiplier = 13.5 / 6 = 2.25
dang this is hard for me, let me think
