x=-28......................
Answer:
division property...im in advanced algebra
Step-by-step explanation:
The answer would be D 95.8.
You have to use the Pythagorean theorem to find the missing side length
So it would be 10 squared plus 12 squared equals 15.62
Then you double it because of the two top side lengths
Then you use the Pythagorean theorem for the bottom
12 squared plus 30 squared which equals 32.31
And you double that as well
31.24 plus 64.62 equals 95.86 and you just round to 95.8

It <u>decreased by 30 cents</u> per week.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The average <em>rate of change</em> is calculated as:
the <u>ratio of the sum of the change</u> in the three weeks <u>divided by</u> <u>the number of weeks. (</u>The <em>number of weeks</em> being <u>3</u>)
<em>Rate of change</em> =
.
(-60 + -10 + -20 = -90). So, to <em>simplify</em> it:
= <u><em>-30</em></u>
