I don’t know what to do

13. 5(m-2)

Your multiplying the number outside the bracket by the ones inside the brackets

so 5×m= 5m

5×-2= -10

so the answer is 5m-10

14. -3×m= -3m

-3×4=-12

= -3m-12

15. h×h= h²

h×-2= -2h

=h²-2h

16. -2z + 16

17. 8y+16

18. a²+ 3a

19. 2m² + 8m

20. -4x²+40x

4 & 3

step-by-step explanation:

factor of 108=2×2×3×3×3=2×2×3^3=the number is 4 because 2 only occurs 2 times and 2×2=4 and factor of 2187=3^3×3^3×3=the number is 3 because 3 onlyvoccur 1 time.
