Answer:

640 cm ^2

Step-by-step explanation:

40x4x4 = 640

let's say b = 20 and h = 4

1/2(20)(4) = 40

scale by 4

b= 80 h = 16

1/2(80)(16) = 640

Hi can you help me pleaseeee?)

<em>So to solve for a variable, you have to isolate that variable onto one side.</em>

<h3>14.</h3>

Firstly, multiply both sides by j: h-4=kj

Next, divide both sides by k and <u>your answer will be: \frac{h-4}{k}=j</u>

<h3>15.</h3>

Firstly, add g on both sides: \frac{x}{5}=a+g

Next, multiply both sides by 5 and <u>your answer will be: x=5(a+g)</u>

<h3>16.</h3>

Firstly, subtract 5p on both sides: 9c=-4p

Next, divide both sides by 9 and <u>your answer will be c=-\frac{4}{9}p</u>

Vilka [71]

Answer:

________________________________

step\:1

\frac{1}{ \sqrt{3} -  \sqrt{2}  }

write the equation

________________________________

step\:2

\frac{1 \times ( \sqrt{3} +  \sqrt{2})  }{ (\sqrt{3} -  \sqrt{2} ) \times  (\sqrt{3}  +  \sqrt{2})  }

multiply both numerator and denominator by √3+√2

________________________________

step\:3

\frac{ \sqrt{3} +  \sqrt{2}  }{ ( 3 ) - ( 2 ) }

after multiplying numerator with √3+√2 we get→√3+√2

after multiplying denominator we get 3-2

________________________________

step\:4

\frac{ \sqrt{3}  +  \sqrt{2} }{1}

after subtracting 3 with 2 we get →1

________________________________

hence denominater is rationalized✓

hope it helped you:)

Answer:

Skewed to the left

Step-by-step explanation:

Given

Median = 3304

Mean = 3204.9

Required

The type of distribution

From the given data, we have:

Median \ne Mean --- Mean and Median are not equal
