S² - 16s - 57 = s² - 16s + 64 - 121 = s² - 2*1*8 + 8² - (11)² =
<span>we use the formula  a</span>² - 2ab + b² = (a-b)²
(s - 8)² - (11)²
<span>we use the formula a</span>² - b² = (a+b)*(a-b)
(s - 8 )² - (11)²
   a²      -   b²
 
[ (S - 8) - 11] * [ (S-8) + 11] = [S-19] * [S+3]

Lubov Fominskaja [6]

Emily has 7 cups of water in a jug.If she drinks 2/3 of a cup every hour.How long would it take her to drink the whole jug
zepelin [54]

It would take her 10.5 hours to drink the whole jug.

Step-by-step explanation:

Given,

Cups of water in jug = 7

Water drunk every hour = \frac{2}{3} of cup

Let,

x be the number of hours.

According to given statement;

\frac{2}{3}x=7

Multiplying both sides by \frac{3}{2}

\frac{3}{2}*\frac{2}{3}x=7*\frac{3}{2}\\x=\frac{21}{2}\\x=10.5

It would take her 10.5 hours to drink the whole jug.

What is the greatest common factor of 28, 48, and 64?
Goryan [66]
First, prime factor all of the numbers. Then, collect the factors which appear in all three lists:

28 = 2 x 2 x 7
48 = 2 x 2 x 2 x 2 x 3
64 = 2 x 2 x 2 x 2 x 2 x 2

The only factor which appears in all lists is 2. It appears twice in the first number, so the greatest common factor in the group is 2 x 2  = 4
