Answer:
(1 -2y)(1 +2y)
Step-by-step explanation:
The difference of squares is factored as ...
... a² - b² = (a -b)(a +b) . . . . . . . . a form you should keep handy
Here, you have a=1, b=2y, so your factored form is ...
... 1 -4y² = (1 -2y)(1 +2y)
Answer:
he traveled a total of 349.5 miles.
Step-by-step explanation:
*First we convert the 150 minutes to hours, that is :

Now we determine the distance Michael traversed during those 2.5 hours:

He transversed 187.5 miles.
We also determine the distance he tranversed the two remaining hours:

He also traveled 162 miles
Finally we add both traversed distances:

So , he traveled a total of 349.5 miles.

Answer:
<u>Option C.</u>
Step-by-step explanation:
See the attached figure which represents the graph of the given options.
To determine if a line represents a valid function, we may use the vertical line test.
If it is touching more than one point on the line at a time, the line is not a valid function.
So, according to the previous rule, the function of figure C is a function and its inverse is also a function.
<u>The answer is option C.</u>
A + E + N = 122
E = 2N
A = 7 + E....A = 7 + 2N
(7 + 2N) + 2N + N = 122
5N + 7 = 122
5N = 122 - 7
5N = 115
N = 115/5
N = 23 <== North America
E = 2N
E = 2(23)
E = 46 <== Europe
A = 7 + E
A = 7 + 46
A = 53 <=== Africa
The only thing i can think would work is 6*7=7*6
42=42
