Answer: D. 6=6
Step-by-step explanation:
9x + 6 =3(3x+2)
9x + 6 = 9x +6
9x - 9x +6 = 6
0x +6=6
6=6
Answer:
2/3
Step-by-step explanation:
Each time 2 parts of red is being used, 3 parts of yellow is used. The yellow depends on the red so 2/3.
Answer: Choice B
(x-1)(x^3+x^2+5x+6)
==========================================
Explanation:
The 1 in the upper left box means that x = 1 is a root of the original polynomial.
So this means x-1 is a factor of the original polynomial.
This is because x = 1 leads to x-1 = 0 after subtracting 1 from both sides.
-----------------
The 0 in the last position of the bottom row shows we got a remainder of 0.
Getting a remainder 0 tells us that (x-1) is a factor of the polynomial. This synthetic division table confirms our initial guess.
The other values in that bottom row (1, 1, 5, 6) form coefficients to the polynomial 1x^3+1x^2+5x+6, or simply x^3+x^2+5x+6
-------------------
So we know that (x-1) and (x^3+x^2+5x+6) are factors
Meaning that,
x^4+4x^2+x-6 = (x-1)(x^3+x^2+5x+6)
You can confirm this by expanding out the right hand side (distribution rule).
Answer:
Each person will receive Land area = 0.467 millimeter
Step-by-step explanation:
Given as,
Total number of people in North America = 5.28 × 10^8
The area of the country is = 2.47 × 10² km = 2.47 × 10^5 meter
Now according to question , Land is divided equally among each people .
So, For 5.28×10^8 people , land available = 2.47×10^5 meter
Then For 1 people , land available = 
Or , Land available = 4.67 × 10^-4 meter
or , = 0.467 millimeter
Hence for each person , Land available is 0.467 millimeter . Answer
