I can't solve this problem

13.9 mm

Step-by-step explanation:

To find the diagonal of the box, x, apply the following formula, d = √(l² + w² + h²)

Where,

d = x

l = 12 mm

w = 5 mm

h = 5 mm

Plug in the values

x = √(12² + 5² + 5²)

x = √194

x = 13.9 mm (nearest tenth)

the radius is 2 times the diameter.

step-by-step explanation:

x^3-4x^2+3x-2/x^2+1

step-by-step explanation:

factor the numerator and denominator and cancel the common factors
