Please rewrite this equation(s) using parantheses than needed
thank you
Answer:
So first term of the standard equation will be
and last term will be 2
Step-by-step explanation:
We have given polynomial 
We have to write this polynomial in standard form
So for writing in standard form we have to multiply this polynomial and then subtraction

So first term of the standard equation will be
and last term will be 2
Answer: Ф = 20
Step-by-step explanation:
sin2Ф = cos (Ф+ 30 )
if sinα = cosβ , then α and β are complementary ,that is they add up to be
.
Therefore : 2Ф + Ф + 30 = 90
3Ф + 30 = 90
3Ф = 90 - 30
3Ф = 60
Ф = 20
There is a one fifth chance of both so there is a 1/25 chance or .04 or 4% chance that this will happen
