Hi!
The table above is showing how to plug in a variable to x. For an example,
5x - 3 =?
when x= 4 would equal 17. How we would get this is substitute x with 4 and use our order of operations.
5(4) - 3 = 20 - 3 =  17
To get 68, we would do this in reverse. We would add 3 to both sides to eliminate the -3 to have a remainder of
5x  =  71
Divide both sides by five to solve for x.
x = \frac{71}{5}
We can also check our math and plug in 17/5 into x
5( \frac{71}{5} ) - 3 =71 - 3 = 68

Find the area hurry plss
erica [24]

Answer:

114m^2

Step-by-step explanation:

At first it looks like you can split this into 3 rectangles, but the easier way is to subtract the area that is cut out from the larger rectangle. In this image, we have an outer rectangle that measures 12m x 14m. In the middle, there is a 9x6 rectangular hole. Subtract the area of the hole from the total area of the rectangle.

Total area = 12 * 14 = 168

Area of hole = 6 * 9 = 54

Area left = Total area - Area of hole

              = 168 - 54

              = 114m^2

What happens to the particles in iodine when you increase
Tju [1.3M]

Answer:

When you have iodine gas at 200 degrees, the temperature and thus pressure as so high, that when cooling down you enter the liquid phase. And when some of this gas then condenses, the pressure drops. So the remaining part of the gas can sublime.
