Answer:
44
Step-by-step explanation:
you would add 15+15 and 12+12 because it is rectangular meaning there are 4 sides 2 for the y angle and 2 for the x angle
4.6 because -3.2+1.4=4.6 negative +positive = positive
You can rewrite your function as

This implies that

Now, we have
, so it counts as a solution.
On the other hand, depending on the coefficient a, b and c, the cubic equation

can have either one or three solutions.
So, we have the solution x=0, and then one or three solutions coming from the cubic part. The equation as a whole thus have either two or four solutions, depending on the coefficients.
I was wrong the answer is A I just realized that
