The solution to a problem involving a complex number is -4+ 32i. Which of the following expressions could be the problem?
Select ALL that apply.
A. (-2 – 4i) (-6 - 4i))
OB.(-2+161)
C. i (4i + 32)
D. -V16 + (V–64.4)
E. (-6 + 44i) - (2 – 12i)

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

your answer would be 12

we need to divide the number of toy dinosaurs, 156, by the number of brothers, 4:

in order to estimate, we can use compatible numbers:

156 ÷ 4

  ↓

160   ÷ 4 = 40        

the correct answer is a).
