Accoriding to the triangle inequality theorem, sum of two sides must be greater then third side .

And here the length of two sides are given, which are 4 and 7 . ANd there sum is 4+7=11.

So the third side must be smaller then 11.

A,C and D are smaller then 11 but B =11. So the correct option is B .

Choose a value for n, and then evaluate n^2.

Sloan [31]

Pick your favorite number and square it.

Squaring a number means you multiply it by itself.

Let's say you picked the number 7

7 squared = 7^2 = 7*7 = 49

Think of a 7 by 7 grid of tiny squares. There would be 49 total little squares to represent the total area. Graph paper might help visualize this.

14 is what percent of 28?

Butoxors [25]

50%. If you divide 28 by 14, (14/28), you’d get 0.5. Move the decimal place two places to the right, and that’s 50% :)
