Answer:

K=12

Step-by-step explanation:

First you know that what ever is being multiplied, it’s being done so by 4.

So you can divide the answer by the coefficient (the number in front of the variable. Which in this case is 4)

48 divided by 4 is equal to 12!

This id hard please help me do this
svlad2 [7]
In this problem, we're going to use the 'PEMDAS' method.

First, we're doing the problem in the parenthesis.
44 - 4 = 40

Next in PEMDAS, we need to do the exponent.
6² = 6 x 6 = 36

Then we would do multiplication, but there is nothing to multiply so we move onto division.
40 / 2 = 20

Now we would add, but there is nothing to add so we move onto subtraction.
20 - 36 = -16

Our final answer would be -16.

Hope this helps!~
