The answer is 3x(4x+3)(4x-3)
w= x + y/z
w-x = y/z
z= y/(w-x)
y = (w-x)z
Fractions are division problems, ex 1/2 is the same as one divided by 2, so if you multiply the denominator you solve for the numerator, and to solve for the denominator just substitute what's on the other side
The domain is -5 I think but I don't belive is true

Answer:
Step-by-step explanation:
Since the ratio is 4x:4x:7x, if we add all those numbers up we get 15. Then we do 75/15 to get what x equals. So we get 5. So x equals 5. Following the rules of multiplication, you do 4(5):4(5):7(5), and simplifying that further, you get 20:20:35. If we add all those values up, we should get 75, and we do!
If you're wondering why I did 4x:4x:7x instead of 4:4:7, it's because a ratio is just a...well ratio? It's easier to visualize if you put a variable because the variable could be anything, and you would have to multiply all the given values to get the same proportions. In summery, I did it so it was easier to visualize
