Not difference of cubes since it is 2nd degree
not difference of squares since it is plus
not sum of cubes because 2nd degreee
answer is square of binomial (why do we even need this property, oh well)
C
Answer:
26
Step-by-step explanation:
Written in the form y = kx.
the constant is k.
you can see that the constant there is 26. it doesn't change.
It's a function because each input has one output
Answer:
±90
Step-by-step explanation:
√(-225) · √(-36) = (15i)·(6i) = 90i² = 90·(-1) = -90
_____
On the other hand, ...
... √(-225) · √(-36) = √((-225)·(-36)) = √8100 = 90
___
If you consider all the roots at each stage, the result is ±90. Since you're working with complex numbers here, it is reasonable to recognize every number has two square roots.
... √(-225) = ±15i
... √(-36) = ±6i
... √(-225) · √(-36) = (±15i)·(±6i) = ±90i² = ±90
