(-8x)+x+(-2x)
-7x+(-2x)
-9x
Answer:
multiplication
Step-by-step explanation:
example:
8.29x10=82.9
8.29x100=129
however many zero's is however many decimal places moved
division does the opposite (it moves it left)
Answer:
18
Step-by-step explanation:
Volume is a product of cross-sectional area and height and relresented as V=Ah where V is volume, A is cross-sectional area and h is height.
For the square, since each has a thickness of 6mm then for 24 of them the height will be 24*6=144 mm
Since the volume and cross sectional area of the triangle should be the same, then the height should also be the same.
Since for the triangle each has a thickness of 8mm then the number requred to achieve a height of 144 mm will be 144/8=18 stacks
Answer:
D, A, B, C
Step-by-step explanation:
D is the smallest number, then it goes A, then B and C is the highest as it is a positive number.
hope this helps!
Answer:

Step-by-step explanation:
The computation of the area of kite ABCD is shown below:
Given data
AC = 10 ;
BD = 6
As we can see from the attached figure that the Kite is a quadrilateral as it involves two adjacent sides i.e to be equal
Now the area of quadrilateral when the diagonals are given
So, it is

where,

So, the area of the quadrilateral is
