What is the solution of 3(n+2)=9(6-n)

n = 4

Step-by-step explanation:

Operate using distributive property to free both expressions from the grouping symbols (parentheses):

3 (n+2) = 9 (6-n)

3n + 6 = 54 - 9n

Now add "9n" to both sides to gather all terms with the unknown "n" on one side of the equal sign:

3n + 9n + 6 =54

12 n +6 = 54

Now subtract 6 from both sides  to have the pure numerical terms on the right hand side of the equation:

12 n = 54 - 6

12 n = 48

Now divide both sides by 12 in order to solve for the unknown "n":

n = 48/12

n = 4

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
