Answer: x=20°
Explanation: Since UTX is a diameter, it is equal to 180°. You can now set up the equation (4x+2)+x+78=180. Then solve for x.
You should get, x=20.
Answer:
x^4 -x^3 -9x^2 -11x -4
Step-by-step explanation:
We can use the zero product property
(x-a) (x-b) (x-c) (x-d) where a b c d are the roots
(x- -1)(x- -1)(x- -1) ( x-4) since the root -1 is repeated 3 times and 4 is a root
(x+1)(x+1)(x+1) ( x-4)
Foil the first two terms and the last two terms
(x^2 + 2x+1)( x^2 -3x-4)
Foil again
x^4 -3x^3 -4x^2 +2x^3 -6x^2 -8x +x^2 -3x-4
Combine like terms
x^4 -x^3 -9x^2 -11x -4
Answer:
Mexico's top free trade agreements are bilateral (two country partnership), and multilateral (three or more country partnership), and include NAFTA, EU, Japan, Pacific Alliance (G3), and Central America
The answer is: [A]: (x + 2) (x² − 2x + 4).

Explanation:
_____________________________
Note the formula:
___________________
a³ + b³ = (a + b) (a² − ab + b²)<span>
_________________________________
x</span>³ + 8 can be written as x³ + 2³ ; since 2³ = 8
______________________________
So, using the formula:
_____________________
a³ + b³ = (a + b) (a² − ab + b²) ;
______________________________
x³ + 8 ; or, x³ + 2³ ; can be factored; where a = x and b = 2.
__________________________________
→ Substitute these values for "a" and "b"; and rewrite:
__________________________________
→ x³ + 2³ = (x + 2) (x² - x*2 + 2²) ;
__________________________________
→ Simplify, and rewrite as:
__________________________________
→x³ + 8 = x³ + 2³ = (x + 2) (x² − 2x + 4) ;
__________________________________
→which is our first answer choice, "[A]".
