Answer:
x ≤ 13/3
Step-by-step explanation:
4 - 3x ≥ -9
Isolate the variable, x. Treat the ≥ sign as an equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 4 from both side:
4 (-4) - 3x ≥ -9 (-4)
-3x ≥ - 9 - 4
-3x ≥ -13
Next, divide -3 from both sides. Note that when you divide by a negative sign, you must flip the sign:
(-3x)/-3 ≥ (-13)/-3
x ≤ (-13)/(-3)
x ≤ 13/3
x ≤ 13/3 is your answer.

Answer:
Area of smaller square: y^2 yards^2,
area of larger square: 4*y^2 yards^2.
Step-by-step explanation:
If the smaller square has a side which length is y yards, its area can be calculated as the square of its side, so:
Area of smaller square = y^2
If the larger square has a side which length is twice as long as the side of the smaller square, its side is equal to 2*y yards, so its area will be:
Area of larger square = (2*y)^2 = 4*y^2
So the area of the smaller square is y^2 yards^2, and the area of the larger square is 4*y^2 yards^2.
