Answer:
To factor something out you've got to divide, so you would take 5x+40 and divide it all by 5
So, 5x/5= 1x
And, 40/5= 8
Your answer is now x+8 when factored
Eccentricity = foci / half the length of the major axis
= 3.5 / 14 = 1/4
Hello!
Distributive property: a(b+c)=ab+ac


Minus and plus sign.

Then multiply by the numbers.


Hope this helps!

<u><em>Answer:</em></u>5n-4
<u><em>Explanation:</em></u><u>The given expression is:</u>

<u>1- Take the negative as a common factor from both the numerator and the denominator. This will give us:</u>

<u>2- Cancel out the negative sign (common factor) from the numerator and denominator. This will give us:</u>

<u>3- Factor the numerator. This wil give:</u>

<u>4- Finally, cancel out the (17n+19) which common in both numerator and denominator. This will give us the final expression:</u>
