So in order to find the counterexample and to prove it, let us do it one by one with the given options above.
A. 22. 22 is divisible by 2 but NOT DIVISIBLE by 6.
B. 18. 18 is divisible by 2 and also by 6.
C. 36. 36 is divisible by 2 and by 6.
D. 12. 12 is divisible by 2 and by 6.
Take note that when we say counterexample, this is the statement that disproves another statement. Therefore, the answer would be option A. 22. Hope that this answer helps.

Answer:

6580cm

Step-by-step explanation:

The answer is 6580cm because....

Step one First let's figure out what the smaller shape's volume is. To do so we need to multiply ( LxWxH ) so 6x5x? it does not list what the height is so we know it has the same height as the larger shape and it's height is 14cm so we will use 14cm. 6x5x14=420cm
Step two Now lets find the Volume of the larger shape. So lets do LxWxH so Lx?x14 it does not give us the length so we need to add up all of the numbers along the line. We got 7cm then 5 from the bottom of the smaller shape and 10cm. all ads up to 22cm so 20x22x14=6160
Finally we add up the following shapes Volume which are 6160+420=6580cm

Please help I don’t get this

Answer:

H = 11m

Step-by-step explanation:

As we know, volume = length * breadth/width * height

Given,

length = 6m

Breadth/width = 3 1/2 or 3.5

Height = ?

So, l * b * h = v

=> 6m * 3.5m * h = 231m

=> 21m * h = 231m

=> h = 231m /21m = 11m

Therefore, height = 11m / 11metres

Hope this helps

Solution:

hypotenuse=p

perpendicular=m

base=n

According to Pythagoras theorem,

h^2=p^2+b^2

So the right answer of your question is m^2+n^2=p^2

Right answer is of option A.

Hope it helps....
