A trapezoid! A trapezoid has no right angle and 1 parallel side
9(x + 1)^4 - 19(x + 1)^2 + 2 = 0
After expanding and re-factoring, we have:
(3x + 2)(3x + 4)(x^2 + 2x - 1) = 0
solutions are x = -2/3, x = -4/3, x = -1 - sqrt(2), x = sqrt(2) - 1
Answer: 5 batches
Step-by-step explanation: 3 1/3 / 2/3 10/3 * 3/2= 5
The answer is x=5 and y=2
The unknown vertex is on the perpendicular bisector of the opposite side. So the x coordinate is the same as that of the midpoint, x=(18+52)/2=35.
