[(-3x2)+(-8x? )] +4x+[8+(-5)
• [3x2 +8x? ]+4x+[3+(-5)
. [3x2+(-8x? )] +4x+ [9+5
· [(-3x2)+(+8xp)] +4x+ [9+51

i dont know sorry

step-by-step explanation:

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.
