5. 5x-5
. ------------------
. 10x²-25x+15
We can first factor 10x²-25x+15, it will turn into (2x-3) and (5x-5)
(if you need help on factoring, please leave a comment)
So the question will be like:
. 5x-5
. ---------------
. (2x-3)(5x-5) The factored answer is the same as the original . number, so the factor answer can replace it.
We know 5x-5 on the top and 5x-5 on the bottom is the same, so they can cancel out, and it will become:
2x-3=0
Then solve
2x-3=0
2x=3
x=2/3
6.

Calculate the number of sides<span>. The interior angles are 120°, so the exterior angles are 180° - 120° = 60°. The exterior angles add up to 360°, so if we divide 360° by 60° we find there are 6 exterior angles.
Hope this helps!</span>
Hey there!
Let's call this "number" x. We want four times the sum of this number and 15 to equal at least 120.
Therefore, we want this number times four plus fifteen to be greater than or equal to 120. We have:
Distribute:
Subtract:
Divide:
Your answer is C.
