\text{Use FOIL method}\ (a+b)(c+d)=ac+ad+bc+bd.\\\\(6r-1)(-8r-3)=(6r)(-8r)+(6r)(-3)+(-1)(-8r)+(-1)(-3)\\\\=-48r^2-18r+8r+3=\boxed{-48r^2-10r+3}

Ok assuming that when he buys the fabric, he cuts pieces off to make it fit, but doesn't sow them in other places to make up the lost area

so
first find the area of tablecloth he needs to buy
area=pir^2
diameter=32
d=2r
r=d/2
r=32/2=16
adds 5 inches extra
16+5=21
r=21
area of cloth=pi21^2
are of cloth=441pi
aprox pi=3.14
area=441 tmes 3.14
area=1384.74


buys cloth with width of 50 and legnth of x
so we need 2 things
1. area of cloth bought>area of tablecloth
2. legnth &width must both be greater or equal to the diameter of the tablecloth (so we can make a circle fit)

new diameter=32+5+5=42 (2 sides)
so
l and w must both be greater than or equal to 42
 
50l>1384.74
divide both sides by 50 to find legnth
l>27.6948
but the legnth must be also greater than or equal to 42
so make l=42 for min legnth
area of cloth bought=lw=42 by 50=42 times 50=2100

so we do

area wasted=area bought-area needed
area needed=area of tablecloth=1384.74
area bought=2100
area wasted=2100-1384.74
area wasted=715.26 in^2


answer is wasted area=715.26 square inches

<h2>Options A, B and C are correct choices. :) !!</h2>

Step-by-step explanation:

We have been given that Mael 15 ml of bleach with 3.75 liters of water to make a sanitizing solution for a daycare.

Let us see our given options one by one to find which could be combinations of volumes of bleach and water for Mael's sanitizing solution.

Let us compare our given volume proportions with volume proportion of Mael's sanitizing solution.  

A. 12 ml bleach and 3 liters of water.

We can see that both proportions are equal, therefore, option A is a correct choice.

B. 6 ml bleach and 1.5 liters of water.

We can see that both proportions are equal, therefore, option B is a correct choice.

C. 3 ml bleach and 0.75 liters of water.

 

We can see that both proportions are equal, therefore, option C is a correct choice.

D. 20 ml bleach and 5.5 liters of water.

 

We can see that our both proportions are not equal, therefore, option D is not a correct choice
