Answer:

Lenght = 13, Width = 4

Step-by-step explanation:

Perimeter:

2(L + W) = 34

=> 2L + 2W = 34

Area:

L * W = 52

L = 2W + 5

L - 2W = 5

----------------------------

How to find the Length:

Now Add:

   2L + 2W = 34

+     L - 2W = 5

-------------------------

  3L            = 39

L = 13

How to find the Width:

L * W = 52

13 * W = 52

W = 4

======================

Length = 13

Width = 4

According to Boyle’s law, PV= K, what was the volume at the time of the first measurement given the following information? Round
Temka [501]
<h2>Hello!</h2>

The answer is:

The first measurement of volume is equal to 835.23 mL.

<h2>Why?</h2>

Boyle's Law equation can be used when the temperature is kept constant, and it establishes a relation between the pressure and volume, showing that when an ideal gas is kept constant, the pressure and volume are inversely proportional.

So, we Boyle's Law equation states that:

P_{1}V_{1}=P_{2}V_{2}

Where,

P_1=FirstPressure\\V_1=FirstVolume\\P_2=NewPressure\\V_2=NewVolume

Now, if we are looking for the first volume measurement, we need to rewrite the equation as follow:

P_{1}V_{1}=P_{2}V_{2}\\\\V_{1}=\frac{P_{2}V_{2}}{P_{1}}

So, substituting the given information and calculating, we have:

V_{1}=\frac{8.59atm*527mL}{5.42atm}

V_{1}=\frac{4526.93atm.mL}{5.42atm}=835.23mL

Hence, the first measurement of volume is equal 835.23 mL.

Have a nice day!

Simplify 6(x + 2) + 7.<br><br> 6x + 9<br> 6x + 15<br> 6x + 19
miss Akunina [59]
3rd one.

6(x + 2) is simply 6x + 12

Do 12 + 7

You will get 19.

Now put that together.

6x + 19, which is option 3

Hope this helped! :D
