Answer:
20.4
96
Step-by-step explanation:
The value of 5x² - 11x + 18 is
5(2.4)²-11(2.4) +18 = 5(5.76) -26.4+18
= 28.8 -26.4+18 = 20.4 (when x = 2.4)
and 5(-3)² -11(-3) +18 = 45+33+18 = 96
(when x = -3)
Answer:
Step-by-step explanation:
1. Parallelogram and rectangle
Sides: The opposite sides of both parallelogram and the rectangle are parallel and are equal.
Angles: Opposite angles of both parallelogram and rectangle are equal and adjacent angles of both parallelogram and rectangle are supplementary.
Relationship: Not all parallelograms are rectangle but all rectangles can be parallelograms.
2. Parallelogram and square:
Sides: Opposite sides of both the square and the parallelogram are parallel, but all sides are same in square but opposite sides are equal in parallelogram.
Angles: Opposite angles of both parallelogram and square are equal and adjacent angles of both parallelogram and square are supplementary.
Relationship: All squares are parallelograms but not all parallelograms are squares.
Answer: -600 arcminutes
Step-by-step explanation:
We know that 1 degree = 60 arc minutes
The given measure of angle = 
Then , by applying the famous UNITARY METHOD , we multiply 60 to the above measure so that it converts into arc minutes.
Thus , 
Hence, is -600 arcminutes.
