The denominator of a rational number is greater than its numerator by 8. if the numerator is increased by 17 and the denominator decreased by 1, the number obtained is 3/2. find the rational number.

numerator = x

denominator = x+8

so, numerator is increased by 17 and denominator decreased by 1.

x+17 / x+8-1 = 3/2

x+17 / x+7 = 3/2

(now, cross multiply)

3(x+7) = 2(x+17)

3x + (3*7) = 2x + (2*17)

3x + 21 = 2x + 34

3x - 2x = 34 - 21

x = 13

therefore, the rational number is 13/20

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
