A square softball has a side length of 20in. What is the length of the diagonal?

20√ 2

Step-by-step explanation:

you can solve it by using the Pythagorean theorem which is a^2 + b^2 = c^2

--> 20^2 + 20^2 = c^2

400+400= c^2

800= c^2

c= 20√ 2

the answer is c. 23/3

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
