AB = square root of 403

Step-by-step explanation:

use the pythagorean theorem to solve for AB.

a^2 + b^2 = c^2

9^2 + b^2 = 22^2

81 + b^2 = 484

b^2 = 484 - 81

b^2 = 403

b = 20.07

i agree because i see the other persons thinking is clear

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
