Step-by-step explanation:
Because 3x+8 is not equal to 3x-5
3x cancel out for both side and +8 is not equal to -5
To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- The<span> rectangular deck has the following dimensions: 12 ft by 14 ft.
- When the length and width are increased by the same amount, the area becomes 288 ft</span>².
2. Therefore, you have:
A=bxh
288=(12x)(14x)
288=168x²
3. When you clear the x, you obtain:
x=√288/168
x=(2√21)/7≈1.31
Answer:
