3(x + 4) = 3x + 4
3x + 12 = 3x + 4
3x - 3x = 4 - 12
0 = -8 (incorrect....no solution)

little tip ...
if it ends with a variable equaling a number, like x = 2 or y = 4, then there is 1 solution.
if it ends with something unequal with no variable, like 0 = -4 or 5 = 7, then there is no solution.
if it ends with something equaling with no variable, like 2 = 2 or 5 = 5, then there is infinite solutions.

The length of a concrete slab is three more than three times the width. It's area is 330 square feet. What is the length of the
marin [14]

Answer:

Width: 10.5 feet

Length: 31.5 feet

Step-by-step explanation:

Let x represent width of the concrete slab.

We have been given that the length of a concrete slab is three more than three times the width. So length of the slab would be 3x.

We are also told that the area of slab is 330 square feet. We can represent this information in an equation as:

x\cdot 3x=330

3x^2=330

x^2=\frac{330}{3}

x^2=110

Now, we will take square root of both sides.

\sqrt{x^2}=\sqrt{110}

x=10.488\approx 10.5

Therefore, the width of slab is approximately 10.5 feet.

The length of the slab would be 3x\Rightarrow3(10.5)=31.5.

Therefore, the length of slab is approximately 31.5 feet.
