Answer:
. It’s because a prime factor of all even numbers is 2. Therefore the prime factors of all even squares includes two, therefore, the square must be even.
2(x^2+6x+9) = 2(x+3)^2
So after divided by (x+3), answer will be:
2(x+3)
Answer:
Step-by-step explanation:
Given
+ x
Multiply x by to create a common denominator
= + x ×
= +
=
The tan(-x) is the same thing as -tan(x). The tangent function is also the same thing as sin(x)/cos(x), right? So let's rewrite that tan in terms of sin and cos:
is the same as
We can now cancel out the cos(x), which leaves us only with -sin(x) remaining. So your answer is A.
Answer:
Step-by-step explanation:
because 8(8)=64 and 8 is the positive square root of 64.
because 17i(17i)=289i^2=-289(-1)=-289.
