    Presuming you mean: (2 + 2√2) / (1 - √2) Find the conjugate of the denominator (1 + √2) and multiply both halves of the fraction by that value: (2 + 2√2)(1 + √2) / [(1 - √2)(1 + √2)] Now FOIL both halves. If you did things right, the irrational components of the denominator should cancel out: (2 + 2√2 + 2√2 + 2 * 2) / (1 + √2 - √2 - 2) (2 +... show more

    These are exactly the same as other questions that you've asked. Are you learning from them or are we just doing your homework for you? Since the sum of all angles in a triangle is 180 and you know one angle is 81.9, then the sum of the other two are: 180 - 81.9 = 98.1 So we have two angles that add to that: x + y = 98.1 And the two angles... show more

Since the sum of all angles in a triangle is 180 and you know one angle is 81.9, then the sum of the other two are: 180 - 81.9 = 98.1 So we have two angles that add to that: x + y = 98.1 And the two angles are in a ratio of 4:5, so: x/y = 4/5 We now have a system of equations that we can solve. Let's simplify the second equation by multiplying both sides by y, and solve for x in the first equation by subtracting y from both sides: x = 98.1 - y and x = 4y/5 Both of the right sides are equal to x, so both of the right sides are equal to each other: 98.1 - y = 4y/5 Multiply both sides by 5: 490.5 - 5y = 4y Add 5y to both sides: 490.5 = 9y Divide both sides by 9: y = 54.5 Now that we have y, solve for x: x = 98.1 - y x = 98.1 - 54.5 x = 43.6 Your other two angles are: 43.6 and 54.5 degrees

    Best answer: If m is an even integer, then you would use m = 2k (where k is any integer, m is then always even) Just thinking through it logically, if m is even, then m^22 will also be even. If m is even, then -3m is even. The sum of two even numbers is always even. Then adding 1 (an odd number) to an even number makes it odd. You probably will... show more
    Best answer: If m is an even integer, then you would use m = 2k (where k is any integer, m is then always even) Just thinking through it logically, if m is even, then m^22 will also be even. If m is even, then -3m is even. The sum of two even numbers is always even. Then adding 1 (an odd number) to an even number makes it odd. You probably will have to go through the work using m = 2k to show that you get 2(something) + 1 at the end, which will show that the result is odd vs. the "logically thinking through it" method. The converse would then be if m is odd, then m²² - 3m + 1 would be even. But this would be false. Thinking through it: m²² would be odd if m is odd. -3m would be odd if m is odd. The sum of two odd numbers is EVEN. Then adding 1 to an odd number is odd. Since all you need to do is show a counter example, set m = 1 and simplify to show the result is not even: m²² - 3m + 1 setting m = 1 ... 1²² - 3(1) + 1 1 - 3 + 1 -2 + 1 -1 The result is odd. So this expression will never give you an even number result as long as m is an integer.

    Not sure what you mean by "not" numbers... The product of three consecutive integers will always be divisible by 6. One of the three numbers will be divisible by 3 and at least one of them will be divisible by 2. Which means that 6 is a factor of the product.

  • Indicate the equation of the line that is the perpendicular bisector of the segment with endpoints (4, 1) and (2, -5). (mx + b = y)?

    First we need to find the slope of the line connecting the two points so we can determine the slope of the perpendicular line. Slope is change in y over change in x, so: (4, 1) and (2, -5) m = (1 - (-5)) / (4 - 2) m = (1 + 5) / 2 m = 6 / 2 m = 3 So the perpendicular slope to this line is -1/3 as the two slopes have to be opposite-reciprocals of... show more
    First we need to find the slope of the line connecting the two points so we can determine the slope of the perpendicular line. Slope is change in y over change in x, so: (4, 1) and (2, -5) m = (1 - (-5)) / (4 - 2) m = (1 + 5) / 2 m = 6 / 2 m = 3 So the perpendicular slope to this line is -1/3 as the two slopes have to be opposite-reciprocals of each other. If the new line has to go through the midpoint of the given segment, we need to find that midpoint. Just find the mean of the x's and the y's: x = (4 + 2) / 2 x = 6 / 2 x = 3 y = (1 + (-5)) / 2 y = (1 - 5) / 2 y = -4 / 2 y = -2 So we have the point (x and y) and the slope of the new line, so we can now solve for the unknown intercept: y = mx + b -2 = (-1/3) * 3 + b -2 = -1 + b -1 = b So the equation of the line making the perpendicular bisector of the given segment is: y = (-1/3)x - 1

  • Indicate the equation of the line through (2, -4) and having slope of 3/5. (mx + b = y)?

    You are give the slope (m) and a point (x and y), so solve for b: y = mx + b -4 = (3/5) * 2 + b -4 = 6/5 + b -4 - 6/5 = b -20/5 - 6/5 = b -26/5 = b The equation is: y = (3/5)x - 26/5
