Step-by-step explanation:
<u>Step 1: Define</u>
x + 3 + 2x = x + 3
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 3x + 3 = x + 3
- Subtract <em>x</em> on both sides: 2x + 3 = 3
- Subtract 3 on both sides: 2x = 0
- Divide 2 on both sides: x = 0

Answer:
A,B,C,D
Step-by-step explanation:
Mark the unknown number as x
Now the long side is x-3 inches
S=long side*short side=(x-3)*2=2x-6 square inches

2x < 12+6
2x<18
x<9
2<4<6<8<9
