The area of a square is its side length squared. So the side length of the square squared is 42, so the side length of the square is sqrt(42). The perimeter of the square is 4 times the side length, or 4sqrt(42), which is approximately 25.92.

Answer:
y ≤
Step-by-step explanation:
We are to put the linear inequality;
7x - 4y ≥ 20
in slope intercept form.
We can rearrange the inequality as;
-4y ≥ - 7x + 20
Dividing throughout by -4 we get;
y ≤
- 5
Note that the inequality sign '≥' changes to '≤' since we divided all through with a negative number.
