Step-by-step explanation:
Answer:
(4+7i)(4-7i).
This is because you FOIL it to get:
16 + 28i - 28i -49i^2.
That equals to 16 - 49i^2, which equals to:
16 + 49
65, which is a real number.
By factor theorem, f(-4)=7,therefore x+4 is not a factor of f..and remainder when decided by x+4 is 7
Answer:
5^2 = 3^2 + x^2 = 4
Step-by-step explanation:
Well, to find that, you would do:
x(1 (+ or -) % interest rate) * Time.
So I believe that would turn to this:
1300(1+0.042)(5.75)
Your 'x' being 1300, your interest growing by 4.2% and the time of 5 years 9 months (5.75)
