Hmm, I believe the answer is 80%.
It is a decrease.
30 - 6 = 24.
24/30 = 80% decrease from Wednesday.
The answer is a words per minute, because the independent quantity is the words
2.25m + 2(2.25m) + 90 cm =
2.25m + 4.50m + 90 cm
6.75m + 90 cm
1 cm = 0.01m...so 90 cm = 90 * 0.01 = 0.9m
6.75m + 0.9m = 7.65m <===
OR..
1m = 100 cm....so 7.65m = 7.65 * 100 = 765 cm <===

Below are the choices that can be found from other source:
<span> −7
20
20 square root 449 over 449
negative 7 square root 449 over 449</span>
The answer seems to be the third one which is 20 square root 449 over 449.
The values are x = 8 and x = -1.
To find the undefined values, we need to know when the denominator is zero.
To do this, we need to factor it and find the value that would make either factor equal to zero.
If factors to: (x - 8)(x + 1)
Therefore, the undefined values would be at 8 and -1.
