denis-greek [22]3 years ago
8 0

Answer:

3

Step-by-step explanation:

(8x + 28) / ((x − 1) (x + 2) (x + 3)) = A / (x − 1) + B / (x + 2) + C / (x + 3)

Multiply both sides by (x − 1) (x + 2) (x + 3).

8x + 28 = A (x + 2) (x + 3) + B (x − 1) (x + 3) + C (x − 1) (x + 2)

If x = 1:

8 + 28 = A (3) (4)

36 = 12A

A = 3

Divide 25kg in the ratio 2:3:5
fgiga [73]
First, add up the parts of the ratio...
2+3+5=10
then divide the whole into individual parts...
25/10=2.5
then multiply the value of 1 part by the amount in the ratio...
2.5 x 2  =5
2.5 x 3 = 7.5
2.5 x 5 = 12.5
so the final ratio is 5kg:7.5kg:12.5kg
Hope this helps :)
