Answer:
B) (4x-5i)(4x+5i)
Step-by-step explanation:
The expression can be treated as the difference of squares, and factored accordingly. That factoring is ...
a² -b² = (a -b)(a +b)
__
Here, we have ...
a² -b² = 16x² -(-25)
a² = 16x² ⇒ a = 4x
b² = -25 ⇒ b = √-25 = 5i
Then the factoring is ...
(a -b)(a +b) = (4x -5i)(4x +5i)

Answer:
Ok, Sir, The answer is D.
Step-by-step explanation:
From the list of possible answers, the sides are 5 and 12 and the hypotenuse is 13, so sin(x) is either 5/13 or 12/13 depending on which of the two legs is opposite to angle x.
Answer:
the answer is
A. Is based on squared deviations from the regression line.
Step-by-step explanation:
since the numerator of standard error if N, squaring the value cannot give negative value. dependent variable are the squared units
