Hmm,
we see that the middle term is negative
that tells us that the factors must also be negative because if they were different signs then they would have to be 0,1, or -1,0 which wouldn't work because x doesn't factor out, well, if c=0, then it would get x=17 and 0 which doesn't work


well


what 2 numbers are 1 apart, and are negative and add to -17
-8 and -9
multily them
72

c=72
x^2-17x+72=0
if we factord
(x-8)(x-9)=0
theh zeroes are x=8 and 9

Roberta needs 12 zippers to make 3 of the same backpacks. If Roberta has 48 zippers, how many of those same backpacks can she ma
yaroslaw [1]
First, you need to find out how many zippers are used to make one bookbag. To do that, you divide the zippers used to make the 3 backpacks.

12 / 3 = 4

So, 4 zippers are used per bookbag. Then, you divide the number of available zippers by four to find out how many bags she can make.

48 / 4 = 12

Roberta can make 12 bookbags.

Kobotan [32]
Missing info:
Turkey Sizes: 
<span>small - 2kg - 3.9kg </span>
<span>medium - 4kg - 5.4kg </span>
<span>large - 5.5kg - 7.2kg </span>
<span>extra large - 7.3kg - 9.2kg </span>

<span>Turkey Prices: </span>
<span>Small / Medium - £5.99 per kg </span>
<span>Large / Extra Large - £4.99 per kg 
</span>
3/4 lb x 14 persons = (3*14)/4 = 42/4 = 10.5 lbs

1 lb = 450 grams

10.5 lbs * 450grams/lb = 4,725 grams

1 kg = 1000 grams

<span>4,725 grams * 1kg/1000 grams = 4725 kg / 1000 = 4.725 kg.

4.725 kg is under the Medium size of the Turkey.

Medium sized turkey costs </span>£<span>5.99 per kg.

4.725 kg * </span>£5.99 per kg = £<span>28.30

A turkey would cost </span> £<span>28.30 for 14 people.</span>
