Answer:
18
Step-by-step explanation:
Write the expression
-2x²y
substitute the real values with x=-3 and y= -1
-2(-3²)×(-1)
-2(9)×(-1)
-18×-1
18
Find the highest common factor
12 = 1, 2, 3, 4, 6, 12
24 = 1, 2, 3, 4, 6, 8, 12, 24
28 = 1, 2, 4, 7, 14, 28
4 bags is needed
3 apple, 6 blueberry, 7 banana in each bag
(3 x 4 = 12 apple) (6 x 4 - 24 blueberry) (7 x 4 = 28 banana)
The <em><u>correct answers</u></em> are:
90°, 180° and 270°
Explanation:
Squares have rotational symmetry at 90°. This can be found by dividing the number of degrees in a circle, 360, by the number of sides, 4:
360/4 = 90
This means that at all multiples of 90, the square will rotate onto itself. This means that 90, 180 and 270 are all correct.
