Identify the error in the student solution shown below. find the correct answer. show how you got your answer. i am struggling to understand 2in(x) = in3(x) - [ in(9) - 2in(3) ] in(x^2) = in(3x) - [ in(9) - in(9) ] in(x^2) = in(3x) - 0 in(x^2) = in(3x/0); division by 0, undefined

Since 0 in ln(3x) - 0 is not a logarithm, the  property of logarithms cannot be used here.

The difference shown cannot be written as a quotient of logarithms.

The step ln(x2) = ln(3x) - (0) reduces to  

ln(x2) = ln(3x).

The possible solutions are 0 and 3, with 0 being extraneous.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

the answer is d. (1.2, -4.7) on edgn

hope this !
