Answer:
the answer is 8 just took the test and 10 was wrong
Step-by-step explanation:
So since you know that x^2-1 is equal to (x-1)(x+1),
you can figure that this factors to
(y^2-x^3)(y^2+x^3)
because you know how the difference of two squares formula, stated on the top line of this answer.
It can’t, we made a chart in my class, with parallelograms and the top and kites and trapezoids are on the same level so they can’t be the same
6 = x + 2
Subtract 2 from both sides
6 - 2 = x + 2 - 2
4 = x
