Answer:
n=18
Step-by-step explanation:
100=4(n+7)
100=4n+28
-28 -28
72=4n
n=18
In case this wasn't easy to understand, first you distribute the 4 to the n and 7, to get 28, after that the equation becomes 100=4n+28, then you subtract 28 from 100, and from itself to get the 4n by itself, you are left with 72=4n, after that you just divide 4n and 72 by 4 and get n=18
hope that helped :)

Answer:
Dear Laura Ramirez
Answer to your query is provided below
Option B is correct
Step-by-step explanation:
In a right triangle, the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.
Also,
By the triangle inequality theorem, the sum of the lengths of any two sides should be greater than the length of the third side.
Here, if you see( 16+24)>38
So, the set of numbers can be measures of a
triangle.
9 over 4 equals 9 divided by 4
