The length is 4 yards longer than 3width so L = 3W+4
perimeter equal 408 yards

perimeter equal 2L +2W = 2(3W+4)+2W 

408 = 6W +8 +2W
400=8W

W = 50

L = 3*50 +4 = 154

L = 154
W = 50

P = 2L +2W
408 = 2*50 +2*154
408 = 100 +308
408 = 408

hope that this is easy understandably

What is a fraction of a fraction

<h3> - - - - - - - - - - - - - ~<u>Hello There</u>!~ - - - - - - - - - - - - - </h3>

➷ When it comes to dividing fractions, there is a rule you must now.

It's called Keep Flip Change.

I'll give you an example:

\frac{2}{7} / \frac{4}{6}

Keep the first fraction exactly as it is

Flip the second fraction upside down (switch the numerator and denominator around)

Change the sign to a multiplication.

This is how it should look:

\frac{2}{7} *\frac{6}{4}

Now you just multiply them as you normally would to get an answer of:

\frac{12}{28}

➶Hope This Helps You!

➶Good Luck :)

➶Have A Great Day ^-^

Make V the subject of the formula E=mv2/2
Dima020 [189]

Answer:

v = ± \sqrt{\frac{2E}{m} }

Step-by-step explanation:

Given

E = \frac{mv^2}{2} ( multiply both sides by 2 to clear the fraction )

2E = mv² ( divide both sides by m )

\frac{2E}{m} = v² ( take the square root of both sides )

v = ± \sqrt{\frac{2E}{m} }
