Let's try to simplify x^2 + 16. It's a sum of two squares:
x^2 + 16 = 0
x^2 = -16
The problem is, we can't take a square root of a negative. This is where imaginary numbers come in.
Remember that square roots have a plus or minus symbol outside:
±√-16 = ±4i
Our two roots are 4i and -4i. Therefore, the trinomial simplifies to:
(x + 4i)(x - 4i)
If we attempt to divide x + 4 by these two binomials, we will find that 4 and 4i are not like terms. Therefore, we can't simplify this expression.
Blake has 25 CD's.
25 times 3 = 75
75 + 7 = 82
Joel has 82 CD's.
If Joel has twice as many as Mariella, then divide 82 by 2 and you get 41.
Mariella has 41 CD's.
Answer: 4n -7
Sam has 4 times than Declan so it would 4n. Amaya has fewer so then you would add the -7 and the equation you get is 4n - 7.
Answer: the many shall not be televised
Step-by-step explanation:
4 3/8 x 2 = 8 6/8
4 3/8 divide 2 = 3/32
6/8 x 4 = 24/32
24/32 + 3/32 = 27/32
