Answer:
A) It warned European countries not to make more colonies in the west.
According to Encyclopedia Britannica, two of the points made by the doctrine include that the Western Hemisphere was not an option for future colonization and that any attempt by a European power to take control of and/or oppress any country in the Western Hemisphere would be seen as an attack against the US.
Step-by-step explanation:
12% and 0.12 are the percentages and deciamls
Answer:
5 less than twice a number is 9. So, twice a number is 14.
They give us 2 pieces to the puzzle. Both are positive numbers...x and y.
1.) 1 number is 1 less than twice another number. (x = 2y -1)...and
2.) the sum of their squares is 106. (x^2 + y^2 = 106).
substitute the value for x into the second equation.
(2y-1)^2 + y^2 = 106
(2y-1) (2y-1) + y^2 = 106 (use distributive property)
4y^2 - 2y - 2y + 1 + y^2 = 106 (subtract 106 from both sides)
4y^2 - 2y - 2y + 1 + y^2 - 106 = 106 - 106 (combine like terms)
5y^2 - 4y - 105 = 0 (factor)
(y-5) (5y-21) = 0 (set to 0)
y - 5 = 0
y = 5
substitute the 5 into the equation for y (x = 2(5) - 1)
x = 9 if we square 9, we get 81.
subtracted from 106 we have 25...the square root of 25 is 5.
our answers are 5 and 9.
