The answer is option B. 11/12 = (13 3/4) /15
it could be considered a true proportion if both are equal in values.
In order to find this, you need to cross multiply the numerator and the denominator in all of those options and find which give the exact result.
11 x 15 = 13 3/4 x 12
165 = 165

Answer: 4(x - 1)(x^2 + x + 1)</h3>
==================================================
Work Shown:
4x^3 - 4
4(x^3 - 1)
4(x - 1)(x^2 + x + 1)
In the last step, I used the difference of cubes factoring formula which is
a^3 - b^3 = (a - b)(a^2 + ab + b^2)
I believe the answer is C. It is the only one that makes sense
We just need to solve the equation in order to find the value.
So we subtract 5 from both sides of the euqation and get
Now we divide by 3 on both sides and get
So the answer is C.
Hope this helps!
