This is exactly like the one with the 'n's that you posted yesterday.
I guess you didn't get enough help on that one to understand it.
<span><u>7k/8 - 3/4 - 5k/16 = 3/8</u>
3/4 is the same as 6/8.
Add it to each side of the equation:
7k/8 - 5k/16 = 9/8
Multiply each side by 16 :
14k - 5k = 18
Add up the 'k's on the left side:
9k = 18
From this point, you can proceed directly to the numerical value of 'k'
if you need it.<u />
In your question, you said you need help, and I showed you how to
strip the problem down so that the only thing left is ' k = something '.
Giving you the answer is no help. Nobody actually needs the answer.

Answer:
(4x - 3)(3x² + 1)
Step-by-step explanation:
Given
12x³ - 9x² + 4x - 3 ( factor the first/second and third/fourth terms )
= 3x²(4x - 3) + 1(4x - 3) ← factor out (4x - 3) from each term
= (4x - 3)(3x² + 1) ← in factored form
Check the picture below.
you can pretty much just count the units off the grid.
the perimeter is the length of all sides summed up.
Answer:
4/27
Step-by-step explanation:
F(x) = 4(1/3)^x
Let x =3
F(3) = 4(1/3)^3
Exponents first
F(3) = 4 * 1/27
Then multiply
f(3) = 4/27
