Answer:
17*2^11
Step-by-step explanation:
Lets start by remembering two property of power.
That is important to remember since 4= 2^2. Hence, the given problem can be written as the following
Analyze Lorena's work to determine which statements are correct. Check all that apply. In Step 1, she correctly distributed –3
to the parentheses. In Step 2, she combined like terms 5k and 2k. In Step 3, she applied the multiplication property of equality to isolate the variable term. In Step 4, she should have multiplied both sides by –1 to isolate the variable. Lorena found the correct solution to the linear equation.

Answer:
The answer is "The correct step are 1, 2 and 4 ".
Step-by-step explanation:
In the question some data is missing so, its correct question can be defined as follows:
In the given equation:
Lorena's steps should be evaluated
In Stage 1: It is right because it allocates – 3 to parentheses appropriately, , that's why she has 5k-6k+2-9=0
In Stage 2: It is right because in this term 5k and 2k are merged, that's why she got -k-7=0
In Stage 3: It is not right because the propagation property of fair treatment was not used.
In Stage 4: It is right because it multiplies the variable on one of the two sides by -1. So, k=-7 to get.
