  • Hi, I'll give an example and then do your problem. Here are rules for the sum and difference of perfect cubes. First, always look first for a GCF. If there is one, factor it out. Then, perfect cube problems will always factor into a binomial t…

  • Hi, If h is the initial height of the helicopter, and x is the distance from the helicopter to the 25° angle, then 100 - x is the distance to the 35° angle. .h --- = tan 25° .x h = x tan 25° ......h ----------- = tan 35° 100 - x h…

  • Hi, 1) Where does y= 1/3x -12 cross the y-axis? Let x = 0. The equation becomes: y= 1/3x -12 y= 1/3(0) -12 y = 0 - 12 y = -12 It crosses at (0,-12). <==ANSWER 2) What is the x-intercept of the line defined by 4x-7y=24 To…

  • Hi, I 2x - 9/2 I = I 7 - 3x I Make 2 equations - one with the expression set equal to each other without absolute vale bars, and then write a second equation with one expression equal to the opposite of the second expression. Then solve both …
  • Hi, ( 6- √6) (3√2 - 2√3) (4√2 + 3√3) / 6 = ( 6- √6) (3√2 - 2√3) (4√2 + 3√3) ---------------------------------------------- = . . . . . . . . . . 6 (18√2 - 12√3 - 3√12 + 2√18)(4√2 + 3√3) --------------------------------------------------…
  • Hi, 1.Write a proportion for the following problem. Use x as the variable. When you type it in, leave no spaces, like this example: 3/4=x/5. Marge drove 348 miles in 4.5 hours. At that rate, how many miles could she drive in 10 hours? 348/4.5…

  • Hi, p and n are integers such that p > n > 0 and p² - n² = 12. p² - n² = 12 (p - n)(p + n) = 12 I. 1 If (p - n) = 1, then p + n = 12 so (p - n)(p + n) = 12 p - n = 1 p + n = 12 ---------------- 2p = 13 p would not be an int…
  • Hi, I'm not sure if I understand your question. This is the way I am reading it: In year 2, the income was 25% higher than it was in year 1. In year 2 income was £2,000,000. If ticketing was 12.5% of the income in year 1, what was the value…

  • Hi, lim 5/3+2e^-x = 5/3 + 0 = 5/3 x-> ∞ lim 5/3+2e^-x = 5/3 + 2e^(positive exponent from -(negative x)) = ∞ x->-∞ I hope that helps!! :-)
  • Hi, Factor the expression inside the radical. . _____________ √x² + 20x + 100 = . ________ √(x + 10)². = x + 10 <==ANSWER I hope that helps!! :-)
  • Hi, The answer is b, -2/3. The reason is that in order for there to be no ordered pair (x,y), the lines must be parallel to each other, which happens when they have the same slope. If you solve the first equation for y, it becomes y = 2/3x - 2…
  • Hi, Combining x² + 12 x and 7x + 90 gives an area of: x² + 12 x and 7x + 90 = x² + 12 x + 7x + 90 = x² + 19x + 90 Since area = length x width, then x² + 19x + 90 = (x + 10)(x+ 9) Since perimeter = 2(length)(width), then perimeter = 2(x…
