Answer:

\boxed{7-26i}

Step-by-step explanation:

The binomials are multiplied in the usual way, using FOIL or the distributive property:

  (5 -2i)(3 -4i) = 15 -20i -6i +8i²

Since i² = -1, this becomes ...

  = 15 -20i -6i -8 = 7 -26i

postnew [5]

Answer:

x = \frac{60}{2.35} or x = 25.531...

Step-by-step explanation:

<u>Step 1:  Cross Multiply</u>

x = \frac{60}{2.35} or x = 25.531...

Answer:  x = \frac{60}{2.35} or x = 25.531...

Karolina [17]

Answer: the maximum number of guests that he can invite would be 9

Step-by-step explanation:

33 + x

if darnel can afford to spend a total of $42 on his retirement party, then

42 = 33 + x

x = 42 - 33 = 9
