Answer:

~Senpi boi here~

Step-by-step explanation:

Multiply all terms by x and cancel:

x+2x+1=1x

3x+1=x(Simplify both sides of the equation)

3x+1−x=x−x(Subtract x from both sides)

2x+1=0

2x+1−1=0−1(Subtract 1 from both sides)

2x=−1

−1

(Divide both sides by 2)

−1

Answer:

a difference of squares

Step-by-step explanation:

Let's write down the expression:

$(a^2)^2 -(b^2)^2$

we can see that this expression is one of the form $x^2 -y^2$ which is the general expression of a difference of squares.

To be more specific and to see why we say this, let's make $x=a^2$ and $y=b^2$

Now, if we substitute this in the general formula, we get:

$x^2 -y^2 =(a^2)^2 -(b^2)^2$

Thus, this expression is a difference of squares.

The table shows the number of miles driven over time. Express the relationship between distance and time in simplified form as a

Talja [164]

Answer:

Relationship between distance and time in simplified form as a unit rate is; $\frac{47}{1}$

Step-by-step explanation:

Unit rate defined as the rates are expressed as a quantity of 1, such as 5 feet per second or 3 miles per hour, they are called unit rates.

Unit rate = $\frac{distance}{time}$

From the given table:

Take any

time = 4 hours and distance= 188 miles

then, by definition of unit rate;

Unit rate = $\frac{188}{4} =\frac{47}{1}$

Since, this is the constant rate.

Therefore, the relationship between distance and time in simplified form as a unit rate is; $\frac{47}{1}$
