Answer: 3 cofficients are there ( 5, 2, and 6).
Answer:
20 square units
Step-by-step explanation:
Point D should be D(4, -1) if a rectangle is to be formed. A picture is attached to this answer.
The rectangle's dimensions are 4 by 5, so it's area is 4 x 5 = 20 square units. The picture is small enough that you could even just count squares inside the rectangle!
2x^2 - 5x + 1 = 3
Subtract 3 from both sides
2x^2 - 5x + 1 - 3 = 3 - 3
2x^2 - 5x - 2 = 0
Use quadratic formula with A = 2, B = - 5, C = - 2
x = - b +- sqrt b^2 - 4ac/2a
x = - ( - 5) +- sqrt (- 5)^2 - 4(2)( - 2)/(2)(2)
x = 5 +- sqrt 41/4
x = 5/4 + 1/4sqrt 41 or x = 5/4 + - 1/4 sqrt 41
Answer: x = 5/4 + 1/4 sqrt 41
x = 5/4 + - 1/4 sqrt 41
Hope that helps!!!!! (D)
