You have to get to equal terms
So you have to multiply top and bottom of the left side by 3-x and you have to multiply top and bottom of the right side by x-3
Answer is -x2 (neg x squared) -6x +9
Answer:
150
Step-by-step explanation:
since a circle is 360 degrees, add up all of the other degrees and then subtract from 360
First, we will get the factors of 32:
32 = 1x32 = 2x16 = 4x8
Now, we will find the arrangements of the tiles
Note: we will exclude that she can can form one column including all 32 tiles or 32 columns with 1 tiles in each as these are the trivial answers.
To find the possibilities, we will use the factors 2, 16, 4 and 8.
Tyra can form:
2 column with 16 tiles in each
16 columns with 2 tiles in each
4 column with 8 tiles in each
8 columns with 4 tiles in each
Roughly 1.7 percent of the bands are shorter than 3cm. We calculate the z score of the data point in standard distribution. By definition of z score, we use score minus mean divided by standard deviation. z=(3-6)/1.5=-2. A z score of -2 corresponds to approximately 1.7%, in other words, roughly 1.7 percent of data is less than 3cm.
