Answer:
x=4
Step-by-step explanation:
-6x+3x=-3x -7-5=-12 . -12 divided by -3 is 4.
36/54=2/3
36/24=2/3
so each time it bounches 2/3 or what it bounced before
seems to be a geometric sequence
an=a1r^(n-1)
a1=first term
r=common ratio
a1=54
common ratio is 2/3
an=54(2/3)^(n-1)
The answer is the second one
( b )
Associate property of addition
I think 18q-4 is the answer
By splitting the shape into a semi-circle and rectangle, we can see that we have a semi-circle with a diameter of 14 cm and a rectangle with dimensions of 28 cm by 15 cm. To find the area of the entire shape, we can add the areas of the two shapes up.
We can find the area of the semi-circle using the formula
, where
is the radius of the semi-circle. In this case, the area would be:

The formula for the area of a rectangle is
, where
is the length of the rectangle and
is the width. In this case, the area would be:

Thus, the area of the total shape is:
