Answer:
the area is 13.5 inches squared and the perimeter is 16 inches
Step-by-step explanation:
because if you add 4.5 + 4.5 + 3.5 + 3.5 that equals 16
and if you multiply 4.5 by 3 equals 13.5 I hope I'm right I hope this helped

Step-by-step explanation:

The new pressure is 2 Kpa
<em><u>Solution:</u></em>
At constant temperature, the pressure of a sample of gas is inversely proportional to its volume
Therefore,
Let "p" be the pressure of sample gas
Let "v" be the volume
Then we get,
Where, "k" is the constant of proportionality
<em><u>I have some oxygen in a 2.28 liter container with a pressure of 5 kPa</u></em>
Substitute v = 2.28 and p = 5 in eqn 1
<em><u>I move all of it to a 5.7 liter container at the same temperature</u></em>
Substitute k = 11.4 and v = 5.7 in eqn 1
Thus new pressure is 2 kPa
Answer:
Put a point at (-7,0) and another at (0,-2)
Step-by-step explanation:
2x+7y=-14
Plug in 0
2(0)+7y= -14
7y=-14
y=-2
same thing for x
2x+7(0)=-14
x=-7
