Answer:

29i

Step-by-step explanation:

From this information, we can write the following equation: (2-5i)(2 + 5i)(i)

We can see that there is the factorization of the difference of squares, so we can first expand that. The equation will become the following: (4+25)(i)

= 29i

hope this helped! :)

  • Answer:

<em>C) 52 m²</em>

  • Step-by-step explanation:

<em>A = 2(lw + lh + wh)</em>

<em>l = 4m</em>

<em>w = 3m</em>

<em>h = 2m</em>

<em>A = 2(4m×3m + 4m×2m + 3m×2m)</em>

<em>= 2(12m² + 8m² + 6m²)</em>

<em>= 2×26m²</em>

<em>= 52m²</em>

BRAINLIEST IF CORRECT 40 POINTS
kati45 [8]

Answer:

D. The checking account is overdrawn by $15.

Step-by-step explanation:

Since the balance on a checking account represents the remaining money left in that checking account, having a negative value for that would mean an overdrawing of money, or drawing more money than is in that account in the first place.

Therefore, the answer would be that the checking account is overdrawn by $15.

Hope this helped!
