Answer:
If (x - 2) is a factor of 2x³ + x² - 3 then for the value of x = 2 the polynomial is equal zero.
Substitute:
2 · 2³ + 2² - 3 = 2 · 8 + 4 - 3 = 16 + 4 - 3 = 17 ≠ 0
<u>Answer: B) (x - 2) is not a factor.</u>
B would be your answer because the chart says 1 shirt equals $25 dollars, 2 shirts equal $40 and 3 shirts equal 55 dollars. On the graph (B) if you find your number of shirts (x) and look up at the line and see that it is in line (y) with the cost that is how u find ur answer. Hope this helped!
Answer: A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.

Answer:
None of the pairs of expressions are equal
Step-by-step explanation:
• 2n ≠ 2 +n
2n is the same as 2 times of n (expressed as a multiplication sign), while 2 +n is the addition of 2 to n.
•n² ≠ 2n
n²= n ×n
2n= 2 ×n
• 2n² ≠ (2n)²
Note that in the latter, there is a bracket which means that the square applies to both 2 and n.
(2n)²
= (2)² × n²
= (2 ×2)(n²)
= 4n²
Thus, none of the pairs of expressions are equal.
Answer:
6045000000000000000000000 kg.
Step-by-step explanation:
We have been given that the mass of Earth is 
kg. The mass of the Moon is 
kg.
To find the total mass we will add mass of Earth and Moon.
First of all let us convert the given masses in standard form.
Therefore, the mass of Earth and Moon is 6045000000000000000000000 kg.
