Answer:
a factor of 2 is shown, but 4 was factored out
Step-by-step explanation:
The difference of squares is factored as ...
a² -b² = (a +b)(a -b)
Then the given difference of squares factors as ...
144x² -100 = (12x)² -10² = (12x +10)(12x -10)
Each of these factors has a factor of 2 that can be factored out:
= (2(6x +5))(2(6x -5))
= (2·2)(6x +5)(6x -5)
= 4(6x +5)(6x -5)
The first factor should be 4, not 2.
Answer:
56
Step-by-step explanation:
if it is lenght by width then you would multiply the two numbers
Vertical angles is the answer
Supplementary means they add up to 180
Adjacent means they are next to each other
Complementary means they add up to 90
So the answer is vertical
Total distance covered is equal to ~
- Number of revolutions × circumference
Hence distance covered = 2200 m = 2.2 km
