Answer:
1/(3x) =(x -2)/(4x^2 +9)
Step-by-step explanation:
The denominator cannot be factored further, so the final form will be ...
A/(3x) + (Bx +C)/(4x^2 +9)
The value of this is ...
(A(4x^2 +9) +(3x)(Bx +C))/(3x(4x^2 +9))
= ((3B+4A)x^2 +3Cx +9A)/(3x(4x^2 +9))
Equating coefficients gives ...
3B+4A = 7
3C = -6 ⇒ C = -2
9A = 9 ⇒ A = 1
Using the found value of A, we find ...
3B +4 = 7 ⇒ B = 1
Then the decomposition is ...
B ∪ (C' ∩ A)
Starting from the inside, C' ∩ A is the intersection of not C, which is everything except the circle C, and A. That's the part I shaded in bright blue.
That's unioned with B, which is just all of the circle B. I shaded the parts of B that I didn't already shade with a grey-blue.
These should all be the same shade; I just made them slightly different for explanation.
If 28 tiles is placed in 7 rows then each row has 4 tiles.
<u>Step-by-step explanation:</u>
The total number of tiles given =28.
The number of rows = 7.
The number of tiles in each row is given by diving the total number of tiles given by the number of rows.
No of tiles in each row= .
No of tiles in each row = .
No of tiles in each row = 4.
Note: You can replace the values according to the given values.
