<h2>
Answer:</h2>
<em>K </em>= -3
<h2>
Step-by-step explanation:</h2>
1. Simplify <em>-k-4k to -5k</em>
-5k=3(k-10)-6(k-6)
2. Distribute Parentheses/Expand
-5k=3k-30-6k+36
3.Simplify 3k-30-6k+36 to -3k +6
-5k=-3k+6
4. Add 3k to both sides
-5k+3k=6
5. Simplify -5k+3k to -2k
-2k=6
6. Divide both sides by -2
k=-6/2
7. Simplify 6/2 to 3
k=-3
Division. Divide 45 by -3
The answer to question, "what is the value of 1/2^-2x^-3y^5 for x=2 and y=-4?" is -512
Answer:
40 feet
Step-by-step explanation:
We know that the area of a rectangle is represented as
, where l is the length and w is the width.
We already know the width, and we know the area, so we can plug these values into the equation.

Our goal is to now isolate the variable l, and to do this we can divide both sides by 6.

Hope this helped!
