Answer:
Step-by-step explanation:
The area of a trapezium is given as;
Area = (a + b)h
where: a is the length of the upper side, b is the length of its base and h is its height.
This implies that; a = x - 4, b = x + 5, h = 2x and area = 351
Thus,
351 = ((x - 4) + (x + 50)) 2x
= (x - 4 + x + 5) x
531 = (2x + 1) x
= 2 + x
So that;
2 + x - 531 = 0
This gives a quadratic equation.

In my understanding, the component form of a vector is the ordered pair that describes the changes in the x- and y-values.
Therefore to get it
you must add all the
x
(0 + (-6) + (-6) + 6)
= -6
Then add all y
(7 + 7 + (-11) + (-11)
= -8
Answer = (-6,-8)
