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.
Answer:
11 people ate at least 1 banana.
*written: seven million.
*expanded: 7,000,000+000,000
The midpoint would be (7, 5)
The midpoint of any two points is simply the average of the x points and the average of the y points. So we'll start by averaging the 2 x points together. To take an average, we add the two numbers together and divide by 2.
X VALUE
4 + 10 = 14
14/2 = 7
Now do the same for y
Y VALUE
22 + -12 = 10
10/2 = 5
Using those answers we can create the ordered pair (7, 5)
