Answer:

16i + 4

Step-by-step explanation:

(2 + 2i)(5 + 3i) =

= 2×5 + 2i×5 + 2×3i + 2i×3i

= 10 + 10i + 6i + 6i²

= 6i² + 16i + 10

= - 6 + 16i + 10

= 16i + 4

(2+2i)(5+3i)
10+6i+10i+6i^2
10+16i+6(-1)
4+16i
When you have an “i^2”, you also have a negative one. The simplified answer is 4+16i

Hello!

In a box plot, the edges of the box represent the lower and upper quartiles. The line dividing the box is the median. The left whisker goes from the minimum to the lower quartile, and the right whisker goes from the upper quartile to the maximum.

First, let's see the box. The lower quartile is 44. The upper quartile is 64. This means the box will go from 44 to 64.

Therefore, our answer is A) the box will go from 44 to 64.

I hope this helps!

A frozen dinner at a grocery store is purchased for $2.20 wholesale and is marked up by 40 percent. A customer wants to buy four
Y_Kistochka [10]
Since the frozen dinner at the grocery store was bumped up by 40%, the new price would have been $3.08
Now, a customer wants to buy 4 frozen dinners, so multiply the price of one frozen dinner by 4.
$3.08 x 4 = $12.32
There is a 9% sales tax put up for the grocery store. You will want to multiply 9% (or .09) times the price of the 4 frozen dinners.
$12.32 x .09 ~ $1.11
Add the sales tax price to the price of the four frozen dinners.
$12.32 + $1.11 = $13.43 
$13.43 will be the amount the customer will pay.
