This is not an equation because it lacks an equal sign....so the only thing we can do here is combine like terms.
4 - 2x - 12 - 2x + 1 =
-4x - 7
Answer:
Step-by-step explanation:
Let's get all of the terms with the 
on the right-hand side of the equation, and everything else on the left-hand side of the equation.
To do this, we should add 
to both sides of the equation to remove the 
from the left-hand side of the equation:
Finally, to get the by itself, we can divide both sides by 
:
Answer:

Step-by-step explanation:
180 minus 73⁰ plus 62⁰
which is 180 minus 135
145⁰
Answer:
<u>f(x) = = (x + √2 i) (x - √2 i) (x - 2 ) (x + 1)</u>
Step-by-step explanation:
The given function is f(x) = x⁴ - x³ -2x -4
factor the polynomial function
f(x) = x⁴ - x³ -2x -4 = (x⁴ - 4) - (x³ + 2x ) ⇒ take (-) as a common from (- x³ -2x)
= (x² + 2 ) (x² - 2) - x (x² + 2) ⇒ take (x² + 2) as a common
= (x² + 2 ) ( x² - x - 2)
= (x + √2 i) (x - √2 i) (x -2 ) ( x+1)
Notes: (x⁴ - 4) = (x² + 2 ) (x² - 2)
(x² + 2)= (x + √2 i) (x - √2 i)
( x² - x - 2) = (x -2 ) ( x+1)
Answer:
Brand A
Step-by-step explanation:
Comment
The question is one of finding out what the unit cost is.
Brand A: $4.59 has a count of 40
Brand B: $3.99 has a count of 30
Brand A
unit = 4.59 / 40 = 0.115
<em>Rounded: 0.12</em>
Brand B
unit = 3.99 / 30 = 0.133
<em>rounded: 0.13</em>
Brand A even with proper rounding is the better buy
