Answer:
2625 dolls
Step-by-step explanation:
Please refer to the attached image for explanations
$30 because 12/6 = 2 so 15 x 2 = 30
The answer is 6.89 because
6.89+14.52=21.41
So 21.41+(-14.52)=6.89
B -13 -34i
(7 + 2i)(-3 - 4i)
Take the 7 then times it buy the second bracket 7x(-3-4i) then take 2i from the first bracket and times it with the second bracket 2ix (-3-4i)
Then keep simplifying
Formula for the area of a quarter circle: A = (pi x r^2) / 4
A = (pi x 2^2) / 4
A = (pi x 4) / 4
A = 4pi / 4
A = 1pi = 3.14 square miles
Hope this helps! :)
