Geometry helps us in deciding what materials to use, what design to make and also plays a vital role in the construction process itself. Different houses and buildings are built in different geometric shapes to give a new look as well as to provide proper ventilation inside the house.
Hope that helped :)
<span>Given that B=(1,2,3,4) how many subsets have exactly two elements?
4C2 =
4! 4! 4 x 3
------------ = -------------- = --------------- = 6
2! (4-2)! 2! 2! 2 x 1
answer is 6</span>
Well the answer should be #3 & #4
Answer:
A. An Algebraic Expression
Step-by-step explanation:
Since we have no equal sign in the problem, we know that it is an expression. An equation has an equal sign and another value so we can simplify to find the value of whatever variable we are working with. We also know that it is not anything numerical because we are working with variables. With this information we will see that the correct answer is A.
Best of Luck!
