Answer:
D.12
Step-by-step explanation:
The first thing is to determine the two integer sets, which we will start with the number 1, therefore the first would be:
{1,2,3,4}
We know that it has a number in common, which in this case would have to be 4, therefore, the other set would be:
{4,5,6,7}
Therefore the sets are:
{1,2,3,4}; {4,5,6,7}
Now to calculate the difference between the sum of the integer between them it would be:
(5 - 3) + (6 - 2) + (7 - 1)
= 2 + 4 + 6
= 12
The answer then would be D.12
Considering the surface area of the spherical ballon, it will take 7 seconds for the the balloon to fully inflate.
<h3>What is the surface area of a sphere?</h3>
The surface area of a sphere of radius r is given by:
In this problem, the surface area is of 
cm², hence the radius in cm is found as follows:
r = 14 cm.
The radius start at 0 cm, inflating at a rate of 2 cm/s, hence it will take 7 seconds for the the balloon to fully inflate, as 14 cm/(2 cm/s) = 7 s.

If the longest side on the similar triangle is 51 and the longest side of the first triangle is 17, then you divide 51 and 17.
51 / 17 = 3
So the similar triangle is 3 times as big.
To find the shortest side of the similar triangle, you multiply 8 and 3.
8 * 3 = 24
The length of the shortest side of the similar triangle is 24.
Hope this helps!
the answer is four and two
