The pentagons ABCDE and PQRST are similar.
Artemon [7]

The value of x, which is the length of ST in the given similar polygons is: 2.4.

<h3>What are Similar Shapes?</h3>

If two shapes are similar to each other, the ratio of their corresponding side lengths would be equal.

Thus, since both pentagons are similar, we would have:

CB/RQ = DE/ST

Plug in the values

5/6 = 2/x

Cross multiply

x = (6 × 2)/5

x = 12/5

x = 2.4

Therefore, the value of x, which is the length of ST in the given similar polygons is: 2.4.

Simplify to the form of a square root of b
yan [13]

Answer:

If we substitute a and b to equal 6 for example

it would be

√

6

2

+

6

2

it would equal 8.5(1.d.p) as it would be written as

√

36

+

36

giving a standard form as

√

72

However if it was

√

6

2

+

√

6

2

it would equal 12 as the

√

and

^

2

would cancel out to give the equation 6+6

Therefore

√

a

2

+

b

2

cannot be simplified unless given a substitution for a and b.

I hope this isn't too confusing.
