Answer:
68cm^2
Step-by-step explanation:
<h2>A trapezium is a type of quadrilateral with the two opposite sides parallel.</h2>
Area of a trapezium= 1/2(sum of parallel sides)×height
Area of the trapezium= 1/2(5+3)×17
Area of the trapezium= 1/2(8)×17
Area of the trapezium=4×17= 68cm^2
Answer:
-45
Step-by-step explanation:
2/3x - 11 = x + 4
- I created an inequality representing the above statement first. This makes things look less complicated than what the question is asking.
2/3x = x + 15
- solve for x. I started by adding 11 to both sides.
-1/3x = 15
- multiply both sides by -3
x = -45
The exact name of the postulate isn't coming to mind, but it's the postulate that any three points that are not on the same line will form a unique plane. A plane in mathematics is a flat surface that extends in all directions.
1485 this is wrong I think
