Answer:
3x+3y and distributive property
Step-by-step explanation:
It is given that
Gretchen buys three bags of apples = 3X
Hayley buys three bunches of bananas = 3Y
As it is also mentioned that it first it is multiplied and then it is added
So, the expression for determining the total number of fruit pieces is
3X + 3Y
And, this expression denotes the distributive property in which we multiplied the each variable and then added it
Answer:
the absoulute value of -7 is 7
3(x-4)=x-6
3x-12=x-6
3x-x = -6+12
2x=6
X= 3
If the lenght of a circle circumference is given by:
![c = 2\pi \times r](https://tex.z-dn.net/?f=c%20%3D%202%5Cpi%20%5Ctimes%20r)
So the lenght of a semicircle circumference is given by the half of it:
![c \: (semicircle) = (2\pi \times r) \div 2 \\ c \: (semicircle) =\pi \times r](https://tex.z-dn.net/?f=c%20%5C%3A%20%28semicircle%29%20%3D%20%282%5Cpi%20%5Ctimes%20r%29%20%5Cdiv%202%20%5C%5C%20c%20%5C%3A%20%28semicircle%29%20%3D%5Cpi%20%5Ctimes%20r)
Radius (R) = 12 ft
![c \: (semicircle) =12\pi \: ft](https://tex.z-dn.net/?f=c%20%5C%3A%20%28semicircle%29%20%3D12%5Cpi%20%5C%3A%20ft)
Answer = 12pi ft of fence.
(4,2) (6,3) (8,4) any of these will work :)
