Answer:
462 pounds
Step-by-step explanation:
weighs 42 pounds
and the water 11 times more
so, 42*11 = 462 pounds
Answer:
x = 1
Step-by-step explanation:
14 -4x = 10
-4x = -4
x = 1
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.
