Independent Variable Question 2.
Dependent Variable Question 3.
Step-by-step explanation:
The arrow is the variable that is controlling, and the independent variable is the outcome of the experiment.
Answer:
84x+50
Step-by-step explanation:
First, you would find the area of the entire square. The area of a square is LW, so you would multiply (7x+6)(7x+6). For this, I would use the FOIL method, so you would multiply the first terms which would be (7x)(7x)=14x^2. Then the outside terms, so (7x)(6)=42x. Then the inside, so (7x)(6)=42x. Finally, the last terms, 6(6)=36.
Then you would combine them, so the area of the whole square is
which would equal
.
Then, the area of the smaller square is (x)(x) which would equal
.
Then you would subtract the smaller square from the bigger one, so the final answer would be
which you could simplify to 
134.84 percent.
Just divide 384 by the other number
