Definitely not D, because one of the x's needs to be negative, and the other should be positive so the x will end up negative when it is multiplied.
I want to say the answer is C. (-x-2i) (x-2i)
Hope this helps :)

Answer:

<h3>Lucas and Zoe will both next visit their mother on 7th of May at the same time.</h3>

Step-by-step explanation:

First, find the first multiple that can be divisible by 5 and 8:

40 is divisible by 5 and 8.

Second, find the days in April and subtract 7 from the days:

April=30 days.

30-7= 23 days.

Finally, subtract 23 from 40 and find it in the next month, which is May:

40-23=17

Therefore, they will both next visit their mother on the 7th of May.

Step-by-step explanation:

DC = DF + FE + EC = 3 + 14 +6 = 23 in $(\because FE = AB)$

Area of trapezoid ABCD

$= \frac{1}{2} (AB + CD) \times BE \\ \\ = \frac{1}{2} (14 + 23) \times 8 \\ \\ = 37 \times 4 \\ \\ = 148 \: {in}^{2}$
