Answer:

1) 24 feet

Step-by-step explanation:

1) area of a square=a^2

perimeter= 4*a

area=36ft^2=a^2

a=\sqrt{36}

a=6 feet

perimeter of the square= 4*6=24 feet

The answer is 8
Here's why:
{ ( \frac{( {6}^{7}) \times ( {3}^{3})  }{(  {6}^{6}) \times ( {3}^{4}  ) } )}^{3}  =   \\ ( \frac{6}{3} ) ^{3}  =  \\ \frac{216}{27}  = 8
The exponents are subtracted one from another when divided.
\frac{ a ^{b} }{ {a}^{c} } =  {a}^{b - c}
We can look at the problem this way:
( \frac{6^{7} }{6 ^{6} }  \times  \frac{3^{3} }{ {3}^{4} } ) = (6^{7 - 6}  \times  {3}^{3 - 4} ) =  \\ ({6}^{1}  \times  {3}^{ - 1} )
Since we have the power of -1 on the 3, we apply this rule:
{a}^{ - b}  =  \frac{1}{ {a}^{b} }
Also this rule because we have the power of 1 on the 6:
{a}^{1}  = a
Then we get this:
(6 \times  \frac{1}{3} )^{3}  = ( \frac{6}{3} )^{3}
We apply the rule:
( \frac{a}{b}) ^{c}   =  \frac{ {a}^{c} }{ {b}^{c} }
We get this:
\frac{{6}^{3} }{ {3}^{3} } =  \frac{216}{27}  = 8

1 Factor completely.
bulgar [2K]

1 Factor completely.

p2+7p+10 = (p + 5)(p + 2)



 2 Factor completely.

x2+10x+16 = (x + 4)(x + 6)


3 Factor completely.

x2+7x−18 = (x + 9)(x - 2)



 4 Factor completely.

x2−5x−24 = (x - 8)(x + 3)



 5 Factor completely.

x2−3x−40 = (x - 8)(x + 5)
