10=2/3n+8<br>what is n ?

alexira [117]

The value of n in the given equation is -2.6

Step-by-step explanation:

Given,

10 = $\frac{2}{3n+8}$

To find the value of n

10 = $\frac{2}{3n+8}$

or, 10(3n+8) = 2 [ by cross multiplication]

or, 30n + 80 = 2

or, 30n = 2-80 [ taking the constant values in one side]

or, 30n = -78

or, n = $\frac{-78}{30}$

or, n = -2.6

hoa [83]

Answer:

4x^2+10x-2=0

Step-by-step explanation:

So the total area of mirror: 2*3 = 6 ft sq

8-6 = 2 ft sq is the area of the frame

x is the thickness of the frame

so we have (2*x)*2+(3*x)*2+x*x*4= 2

4x+6x+4x^2=2

-> 4x^2+10x-2=0
