Apply the indicated operation to the matrix.

will mark brainliest, anyone pls?

your answer is D.

-3  -2  -1

 0  3  6

Step-by-step explanation:

the number on the left of the indicated operation is the original set

the number '3' next to R shows that you need to multiply certain numbers by 3

the subscript on the R's shows which row the multiplication needs to be done on...

in this case the row is 2, and you need to multiply it by 3

so the first row will stay the same: -3  -2  -1

but the second row will change to: 0  3  6

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
