Answer:
$1.23
Step-by-step explanation:
To find how much they should charge, you have to find how much toilet paper they are selling compared to the bulk store. They are selling 6/72 or 1/12 of the rolls, meaning they should charge 1/12 the amount. To find this, simply divide 14.75 by 12, which is ~1.23$.
1a.) ??
1b.) SA = (2.24*1.5)*4+(3^2)
2.) (6*12)+(3.6*4)2
6*12 because the length of the sides of the three inner rectangles are equal to 6 and 4*3, which is 12.
3.6*4*2 because if you cut the triangles and shape them into rectangles, you get side lengths of 3.6 and 4, and then you multiply by 2, to account for the other triangle.
3a/b.)??
(x-9)²=-3+x
expand
x²-18x+81=-3+x
minus x both sides and add 3
x²-19x+84=0
factor
what 2 numbers multiply to get 84 and add to get -19?
-7 and -12
(x-7)(x-12)=0
set equal to 0
x-7=0
x=7
x-12=0
x=12
the number is 7 or 12
both work
