mhm like how x - 4x = -3x :)

OpenStudy (anonymous):

i dont get

jigglypuff314 (jigglypuff314):

square roots work like variables in this sense :) if x = √10 and x - 4x = -3x

OpenStudy (anonymous):

so B :)

jigglypuff314 (jigglypuff314):

yep :)

OpenStudy (anonymous):

What is the measure of angle A in the triangle below

OpenStudy (anonymous):

can u check this for me

jigglypuff314 (jigglypuff314):

correct! :)

OpenStudy (anonymous):

yayyyy! :D

jigglypuff314 (jigglypuff314):

√500 = √5 √100 what is √100 = ?

OpenStudy (anonymous):

10

jigglypuff314 (jigglypuff314):

therefore √5 √100 = 10√5

OpenStudy (anonymous):

B (:

OpenStudy (anonymous):

jigglypuff314 (jigglypuff314):

square both sides to get 6x + 8 = 7x - 6 do you know how to solve it now? :)

OpenStudy (anonymous):

x=14

OpenStudy (anonymous):

C right :/

jigglypuff314 (jigglypuff314):

yep :)

OpenStudy (anonymous):

yayy! (:

√128 = √(64 * 2) = √64 √2 = 8√2

OpenStudy (anonymous):

B ^.^

tan = opposite / adjacent opposite = 12 adjacent = 16

OpenStudy (anonymous):

jigglypuff314 (jigglypuff314):

well, there's different ways to do this... I plugged in inverse tan (24/7) =

OpenStudy (anonymous):

hmm

OpenStudy (anonymous):

i thin k c

jigglypuff314 (jigglypuff314):

mmm http://www.wolframalpha.com/input/?i=+inverse+tan+%2824%2F7%29

OpenStudy (anonymous):

it could be D

OpenStudy (anonymous):

my last question before i go to bed, i dont understand this

jigglypuff314 (jigglypuff314):
