Answer 2

√(14q) 2√(4q)
= 2 √(14 * 4 * q *q)
= 2 √(4) √(q*q) √(14)
= 2*2*q √(14)
(simplify)
* means multiplication

Answer 3

sorry i was eatingh

Answer 4

it's alright :)
did you understand tho?

Answer 5

:) & no can you explain

Answer 6

its B

Answer 7

like how √5 √3 can be combined to equal √15
√(14q) 2√(4q) can be combined to equal 2√(14 * 4 * q * q)
which by the same rule can be separated into 2 √(4) √(q*q) √(14)

and yeah it's B :)

Answer 8

oh thank you, yay can you help me some more :/

Answer 9

so to solve for a for a = √(-2a) square both sides
to get a² = -2a then add 2a to both sides
so a² + 2a = 0 then factor out an a
so a(a+2) = 0 what would a equal?

Answer 10

D

Answer 11

mmm not quite :)
once you find what a equals
plug it into the original equation
if you get something like 2 = -2 then the number you plugged in is extraneous

Answer 12

hmmm i think A

Answer 13

mmm
if you plug in 0 into a = √(-2a)
you would get 0 = √(0)
simplifies to 0 = 0 which is true
so not A :)

Answer 14

hmm :/

Answer 15

C :D

Answer 16

correct! :)

Answer 17

yayy :D

Answer 18

for this, think of the square roots like variables
what would you get if you added 4x + 5x = ?

Answer 19

9

Answer 20

D

Answer 21

yep! :D

Answer 22

yayyyy :D

Answer 23

√(10/121) can be like (√10) / (√121)
so then what is √121 = ?

Answer 24

11

Answer 25

yep :)
so you're left with √10 / 11

Answer 26

C

Answer 27

yep :)
and I gtg now, talk to ya later! It's been nice working with you <3

Answer 28

okay ya thank you :D see ya later, you tooo ^__^
