Answer:
Step-by-step explanation:
lets foil it and complete the square
x^2+4x-12x-48=9
x^2-8x=57
(-8/.5)^2=16
(x-4)^2-73
Answer:

Step-by-step explanation:
It appears you're trying to simplify ...

The final factor cancels the denominator of the fraction, so we have ...

_____
The applicable rules of exponents are ...
(ab)^c = (a^c)(b^c)
(a^b)(a^c) = a^(b+c)
(a^b)^c = a^(bc)
Complementary angles sum to 90 degrees.
90 - 50.1 = 39.9 degrees
Option 4
6_2/5 + (3(1/4)_3/8 + 1/2
<span>2√7 - (-8√7) - 3√7 = </span><span>2√7 + 8√7 - 3√7 = (2 + 8 - 3)</span><span>√7 = 7</span><span>√7</span>
