Given that a/x =12-3a,find the value of x when a=8
monitta
8 / x = 12 - 3(8)
8 / x = 12 -24
8 / x = -12 
x = -0.66666666667

Check your work

8 /(-0.66666666667) = 12- 3(8)
-12 = 12 - 3(8)
-12 = -12

x = -0.66666666667 Exactaly (Ten 6's One 7)

Hope this helps :)

Given a ≠ ± b and (a^2-b^2) / (a+b)=12 find a-b.
grigory [225]

Answer:

\sqrt{12a  \:  +  \: 12b \:  -  \: 2ab \:  +  \: 2b {}^{2} }

Step-by-step explanation:

(a²-b²) / (a+b) = 12

a² - b² = 12(a+b)

(a-b)² + 2ab - 2b² = 12a + 12b

(a-b)² = 12a + 12b - 2ab + 2b²

a - b =

\sqrt{12a \:  + 12b \:  - 2ab \:  +  \: 2b {}^{2} }
