Asp me on these qustion look at each pic for the qustions

Pet show question:

40 dogs in total. They need 4 minutes each and 1 minute for cleaning.  Each dog needs 5 minutes each.  

40 (4+1) = 160 + 40 = 200 minutes

Question 10:

(20-12)6-5(5-3)

Distribute (multiply) the 6 to the left parentheses and -5 to the right parentheses.

20 * 6 = 120    -12 * 6 = -72    -5 * 5 = -25    -5 * -3 = 15

120 - 72 - 25 + 15 = 48 - 25 + 15 = 23 + 15 = 38

Austin and the museum question:

$5.45 and $4.75 per person.  Austin and 5 siblings = 6 people

6 ( 5.45 + 4.75 )

Distribute (multiply) the six to everything in the parentheses

32.7 + 28.5 = $61.20

Dee and lillies question:

3 lillies are on each table. There are 10 tables in total.

3 * 10 = 30 lillies needed

Each lilly costs $0.92.  Multiply 30 lillies by how much they cost.

30 * 0.92 = $27.60

Last question:

2(24 + 9) + 2(15 - 8)

Distribute (multiply) the 2 to the 24 and 9 and the other 2 to the 15 and -8.

2 * 24 = 48   2 * 9 = 18   2 * 15 = 30   2 * -8 = -16

48 + 18 + 30 - 16 = 66 + 30 - 16 = 96 - 16 = 80

I really hope this helps.

i think the answer is 35 i hope you get it right and get a A PLUS I HOPE IT HELPS

i found two solutions,   n = 2 • ± √3 = ± 3.4641
