If the cube shown is 1 centimeter on all sides, what is the length of the diagonal, X, of the cube? (rounded to the nearest tenth)
1.5 cm
1.7 cm
1.9 cm
2.2 cm

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
