(2x + 3)/3(x + 1)^2 + (x - 7)/3(x^2 - 1) (2x + 3)/3(x + 1)^2 + (x - 7)/3(x - 1)(x + 1) LCD = 3(x + 1)^2(x - 1) Take it from here.

Question 1 The domain is all the x-coordinates in any given point in the form (x, y). So, the domain is {3, 5, 7, 8}. Question 2 The answer is no. Why no? The value of the x-coordinate cannot be repeated. We can see that the point (0.3, 0.6) and the point...

(leg)^2 + (leg)^2 = (hypotenuse)^2 Let leg = s Let d = hypotenuse s^2 + s^2 = d^2 2s^2 = d^2 sqrt{2s^2} = sqrt{d^2} s•sqrt{2} = d You can use d = s•sqrt{2} to find the length of a diagonal of any square. I hope this helps.

Let 33 1/3% = 100/3 (100/3)(p) = 19 Note: The word "of" means to multiply. The word "is" means equal. (100p)/3 = 19 Multiply both sides by 3. 3*(100p/3) = 3(19) 100p = 57 p = 57/100 This is the correct answer. Bosnian forgot to divide both sides by 100 t...
