The rectangle below has an area of 14x^4+6x^214x 4 +6x 2 square meters. The width of the rectangle (in meters) is equal to the g
valina [46]

Answer:

<u>Width = 2x² ,  Length = 7x² + 3</u>

Step-by-step explanation:

The area of the rectangle = 14x⁴ + 6x²

The width of the rectangle (in meters) is equal to the greatest common monomial factor of 14x⁴ and 6x²

Factors of 14: 1 * <u>2</u> * 7

Factors of 6:  1 * <u>2</u> *     *3

∴ The greatest common monomial factor of 14 and 6 = 2

Factors of x⁴: x , x² , x³ , x⁴

Factors of x²: x , x²

∴ The greatest common factor of x⁴ and x² = x²

∴ Width = 2x²

∵ Area = length times  the width

∴ Length = Area/Width

Length = \frac{14x^{4}+6x^2 }{2x^2} =\frac{2x^2*(7x^2+3)}{2x^2} =7x^2+3

Question is in the image
nekit [7.7K]

Answer:

The answer is:

f(x)=2x^{2}-8x+6

Step-by-step explanation:

The equation of a parabola in the intercept form is given by:

y=a(x-p)(x-q)

Where:

p and q are x-intercepts

Now, we know the parabola intercepts at x=1 and x=3.

So we will have:

y=a(x-1)(x-3)

Using the point (-1,16) we could find the value of a.

16=a(-1-1)(-1-3)

16=a(-2)(-4)

16=8a

a=2

Therefore, the equation is:

y=2(x-1)(x-3)

y=2(x^{2}-4x+3)

y=2x^{2}-8x+6

<u>The answer is: </u>

f(x)=2x^{2}-8x+6

I hope it helps you!

How do u find the unit rate? <br> Pls explain it with 18 miles in 3 hours <br> thx
Tomtit [17]
Let's turn this into a fraction using the given information we already have.

\frac{18}{3}  \frac{miles}{hour}

We want the denominator, or the bottom part of the fraction, to be 1 in order for us to have a unit rate.

This fraction can be simplified if we divide both the numerator and denominator by 3.

Numerator: 18/3 = 6

Denominator: 3/3 = 1

Now we have

\frac{6}{1} \frac{miles}{hour}

Any number divided by 1 is equal to that number.

6 \frac{miles}{hour}

Thus, your unit rate is 6 miles per hour.

Have an awesome day! :)
