What is the length of the diagonal of the square shown below? ​

5√2

Step-by-step explanation:

By the Pythagorean theorem,

A² + B² = C²

5² + 5² = C²

25 + 25 = C²

C² = 50

C = √50

C = √(2 • 25)

C = √2 x √25

C = √2 • 5

C = 5√2

step-by-step explanation:

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
