Answer:
Step-by-step explanation:
A=hb b/2
Area=height(b) b/2
It will be .6 because u divide
Write 210 as it's prime factors
21 x 10
3x7x2x5
Normally you would look for pairs in the prime factors and put those on the outside of the root, but since there are no pairs for 210 it can't be simplified past the square root of 210.
A, C, and E. This is because dilations change the size/length of the sides = the sides cannot be congruent, however the angles are the same.
Using the arrangements formula, it is found that they can stand in the line in 80,640 ways.
<h3>What is the arrangements formula?</h3>
The number of possible arrangements of n elements is given by the factorial of n, that is:
In this problem, we have that:
- The 2 freshmen are in 2! positions, in any of the 8 positions from 1 to 8.
- The other 7 students are arranged in 7! positions.
Hence the number of ways in which they can be lined up is given by:
N = 2! x 8 x 7! = 80,640.
