Answer:
The president's approval rating in 2014 is 60.9%
Step-by-step explanation:
The parameters given are;
President's approval rating in 2015 = 42%
President's approval rating in 2015 = 31% less than 2014 president's approval rating
Therefore, whereby the president's approval rating in 2014 = x, we have;
42% = x - 31% of x = x - 0.31·x = 0.69·x
Hence, x% = 42% ÷ 0.69 = 60.8696 ≈ 60.9%
The president's approval rating in 2014 = 60.9%.
X^2 - 12x = 61
Take half of the coefficient of the middle term (half of -12x), square this result, and then add, and then subtract, from -12x:
x^2 - 12x + (6)^2 - (6)^2 = 61
(x-6)^2 - 36 = 61, and so (x-6)^2 = 97
Note: These results are all equivalent; choose the one you think best.
Answer:
4pi x 3^2 / 3pi
Step-by-step explanation:
Answer:
X is 6.
Step-by-step explanation:
Because 42 minus 2 is 40 so therefore the answer has to be 40. So what you do is figure out the number that is X to get 40. In that case, it would be 6. 6 times 6 is 36 plus the 4 and you get 40.
