Simplify completely quantity x squared plus 4 x minus 45 all over x squared plus 10 x plus 9 and find the restrictions on the va
dem82 [27]
(x² + 4x - 45)/(x² + 10x + 9) 
<span>
Numerator = N = x² + 4x - 45 </span>
= x² + 9x - 5x - 45 
= (x² + 9x) - (5x + 45) 
= x(x + 9) - 5(x + 9) 
= (x + 9)(x - 5) 
<span>
Denominator = D = x² + 10x + 9 </span>
= x² + x + 9x + 9 
= (x² + x) + (9x + 9) 
= x(x + 1) + 9(x + 1) 
= (x + 1)(x + 9) 
<span>
Hence, the given expr. = N/D </span>
= {(x + 9)(x - 5)}/{(x + 1)(x + 9) 
= (x - 5)/(x + 1) 
<span>
Restrictions : x ≠ - 1, x = 5 </span>

How many different arrangements can be made using all of the letters in the word Iowa?
Alika [10]
1. Check the tree diagram in the attached picture.

2. The first Letter can be one of the letters I, O , W or A. Assume your first letter is I, then you have 3 choices for the second letter, that is O, W or A.

3. Assume you pick O, then you have 2 options for the third letter; W or A. 

4. If you pick A, then the last letter can only be W. 

5. the path described is the "red line path" in the picture; that is the arrangement IOAW.

6. Another path is the "dashed line path" IAOW.

7. We count 6 "paths", where I is the first letter, each "path" standing for one arrangement. 

8. 4*6=24 is the total number of paths, that is arrangements of the letters IOWA.

9. Remark: The first choice is 4, combined (multiplied) by 3 choices for the second letter, combined (multiplied) by 2 choices for the third and finally multiplied by 1.

10. Thus there are 4*3*2*1 arrangements of 4 (different) letters.
