2L + 2W = 32  

L*W  = 64   L = 64/W

2(64/W) + 2W = 32

128/W + 2W = 32

128 + 2W^2 = 32W

2W^2-32W+128 = 0           solve

W = 8

8L = 64                     Plug W into an equation

L = 8

How do I simplify this exponent problem???
Nikolay [14]

Hello from MrBillDoesMath!

Answer:

(3/4) a^(-5)b^(-3)c^2


Discussion:  

(18 a^-3b^2c^6)/ (24 a^2b^5c^4) =

(18/24) a^ (-3-2) b^(2-5) c^(6-4) =

                  as  a^-3/a^-2 = a ^ (-3-2) = a^(-5), for examples

(3/4) a^(-5)b^(-3)c^2


Thank you,

MrB

Please help me. I bad brain
icang [17]

Answer:

The third X is 6. The fourth Y is 4.5

Step-by-step explanation:

The Rule : X is twice as large as Y. Y is half the size of X.

You can get this piece of information by looking at the different values.

For example, y=1 is x=2. This follows the rule. x=4 is y=2.

We have confirmed the rule is true, now we just need to carry the information into the other blocks!

Best of luck on the quiz! Please give brainliest if I helped you out!

Find the distance between the two given points. (-6, -5) and (2, 0)
Ipatiy [6.2K]

Answer:

The answer is

<h2>\sqrt{41}  \:  \:  or \:  \:  \: 6.403 \:  \:  \: units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{( {x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-6, -5) and (2, 0)

The distance is

d =  \sqrt{ ({ - 6 - 2})^{2} +  ({ - 5 - 0})^{2}  }  \\  =  \sqrt{ ({ - 4})^{2}  +  ({ - 5})^{2} }  \\  =  \sqrt{16 + 25}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

We have the final answer as

\sqrt{41}  \:  \:  or \:  \:  \: 6.403 \:  \:  \: units

Hope this helps you
