Hello!
<u><em>Answer:</em></u>
<u><em>w=12</em></u>
<u><em>*The answer must have a positive sign.*</em></u>
Step-by-step explanation:
First, you add by 5 from both sides of an equation.
Then, you simplify.
Next, you multiply by 3 from both sides of an equation.
And finally, simplify and solve. You can also multiply by the numbers from left too right.
Final answer: → 
Hope this helps!
Thanks!

Answer:
False.
Step-by-step explanation:
The number 5 IS a coefficient because it is the first number in the expression.
Answer:
this doesnt make sense
Step-by-step explanation:
Answer:
If this is a true or false
Step-by-step explanation:
It’s true
The correct answer is C: 1/(x + 4)(x - 5)
Why? Well, let's first simplify x^2 - 3x - 10 and x^2 + x - 12; the two denominators. Each of these should become an (x +/- number), and to figure out the number, as well as whether it is positive or negative, we can do a simple trick
Look at the factors of the right number (In this case, -10 and -12)
-10 -12
1 * -10 1 * -12
-1 * 10 -1 * 12
-2 * 5 -2 * 6
2 * -5 2 * -6
-3 * 4
4 * -3
Now for part 2
Which of these pairs add up to the middle number? One of the pairs of -10 should make -3, and likewise, one of the pairs of -12 should make 1 (when x has no number in front of it you may safely assume it is 1).
2 - 5 = -3 and 4 - 3 = 1, so we now know that the 2 fraction equations simplified is
x + 2 / (x + 2)(x - 5) * x - 3/(x -3)(x + 4)
Notice anything repeating? As long as they are apart of the same fraction, we can cross out anything that has the same x - number. Crossing out both x + 2 and x - 3, we now simply have x - 5 * x + 4. Because we crossed out both numerators, the top numbers both become 1, thus giving our answer, C.
