Let's simplify them top to bottom.

6(x + 2) < x - 3
6x + 12 < x - 3
5x + 12 < -3
5x < -15
x < -3
This one checks out.


3 + 4x <= 2(1 + 2x)
4x + 3 <= 4x + 2

This is a problem. In no world is 4x + 3 ever less than or equal to 4x + 2. This one has no solution.

The length of a rectangle is 4 yd longer than its width.
xenn [34]

Answer:

Area = 77 yd²

Step-by-step explanation:

Width = w

Length = w+4

Perimeter =36

Perimeter = L + L + w + w

36 = w+4+w+4+w+w

4w+8 =36

Subtract 8 from both sides

4w = 36 - 8

4w =28

Divide both sides by 4

W= 28/4

W= 7yd

Therefore length = w+4 = 7+4 = 11 yd

Area = length x width

Area = 11× 7

Area = 77 yd²
