1/9

Answer 19

thats the exponent of the answer

Answer 20

how abou ths one?
Simplify (7 – 2i) – (3 + 9i)

Answer 21

Hint: (7 – 2i) – (3 + 9i) = 7 – 2i – 3 - 9i

Answer 22

4-11i

Answer 23

good

Answer 24

don't forget, when you're distributing that negative through, it has to go to each term inside

Answer 25

solve sqrt x+3-3=x

Answer 26

sqrt(x+3) - 3 = x

sqrt(x+3) = x+3

x+3 = (x+3)^2

x+3 = x^2+6x+9

I'll let you finish

Answer 27

x=-2 x=-3

Answer 28

now check those potential answers

Answer 29

-3 doesnt work

Answer 30

whys that

Answer 31

wait -3=-3

Answer 32

so that confirms -3

Answer 33

what about -2
