I need to find a number that the "n" represents. The problem is 9/12=n/32
likoan [24]

The given equation is

\frac{9}{12} = \frac{n}{32}

Here we have to solve for n. First we need to get rid of the denominators and for that we do cross multiplication .

9*32 = 12n

Now we need to isolate n. And for that we need to get rid of 12, by dividing both sides by 12

\frac{9*32}{12}=n

\frac{288}{12} =n

n=24

And that's the required value of n .

PLEASE HURRY<br><br> 9x^2 + 64 = 0<br><br> I NEED THE WORK SHOWN IN ORDER TO GET CREDIT
seropon [69]

Answer:

x = ± \frac{8}{3} i

Step-by-step explanation:

subtract 64 from both sides

9x² = - 64 ( divide both sides by 9 )

x² = - \frac{64}{9} ( take the square root of both sides )

x = ± \sqrt{-64/9} = ± \frac{8}{3} i
