The expression to be simplified is: (9x^2 - 25) / (3x + 5)
We first factor the numerator: 9x^2 - 25 is a difference of two squares, (3x)^2 - (5)^2, so this can be factored into (3x + 5)(3x - 5).
Then the expression becomes (3x + 5)(3x - 5) / (3x+5), and the 3x + 5 term cancels out, leaving just 3x - 5 as the final answer.

Answer:
There is one solution.
x = -17
<em>Proof and step-by-step explanation:</em>
Step 1: <em>Add the numbers</em>
3x-7 = 4+6+4x
3x-7 = 10+4x
Step 2: <em>Move</em><em> </em><em>terms</em>
3x-7 = 10+4x
3x-4x = 10+7
Step 3: <em>Collect the like terms and calculate the sum</em>
3x-4x = 10+7
-x = 17
Step 4: <em>Change the sign by multiplying both sides by -1</em>
-x (×-1) = 17 (×-1)
x = -17
I hope this helped ! :)
Answer:
A: 4
Step-by-step explanation:
You see,, in ratios, the divisor is always the same and in our case, it's 3 . you just divide 12 with the divisor
