Answer:
Answer is A U B = {3,5,7}
Answer:
<em>The second choice is correct. It can be factored as:</em>

Step-by-step explanation:
<u>The Difference of Squares Method for Factoring</u>
The expression:

Is a widely used method to factor binomials that are expressed as the subtraction of two perfect squares.
The condition for a binomial to be factored by using this method is that both terms must have an exact square root and they must be subtracted.
The last two choices are not valid because they are not a subtraction but an addition.
The first choice is not valid because none of the terms is a perfect square.
The second choice is correct. It can be factored as:

the boiling point of jet fuel is 329 degrees F. Rounded to the nearest degree, what is the temperature in degrees Celcius? Use the Formula: C = 5/9(F - 32), where C represents degrees celcius, and F represents degrees fahrenheit.
A). 165 degrees C
B). 183 degrees C
C). 201 degrees C
D). 535 degrees C
Solve:
C = 5/9(F - 32)
Simplify both sides:
C = 5/9(329 - 32) = 0
Simplify:
5/9
Equation at end of step 1:
C - (5/9 * 297) = 0
C - 165 = 0
Solve single variable:
C - 165 = 0
Add 165 to both sides:
C = 165
Therefore, Your answer would be, Letter Choice (A), (C = 165 degrees C
Hope that helps!!!!! Have a great day!!!!! : )
Answer:
(3,2)
Step-by-step explanation:
Since both equations are equal to each others.
2x-4=-2x+8
2x+2x=8+4
4x=12
x=3
Substitute x = 3 in any given equations but I will substitute in the first equation.
y = 2(3)-4
y = 6-4
y = 2
