The area of the rectangle shown is 2x^2-x-15 square units. What is the width of the rectangle?

yuradex [85]

Answer:

<h2>The width is (2x + 5) or (x - 3)</h2>

Step-by-step explanation:

The formula of an area of a rectangle:

$A=lw$

l - length

w - width

We have

$A=2x^2-x-15$

$2x^2-x-15=2x^2+5x-6x-15=x(2x+5)-3(2x+5)\\\\=(2x+5)(x-3)$

Which of the following ratios is not equivalent to the ratio 5/6 Explain

uranmaximum [27]

10/12 = 2*5 / 2*6 = 5/6
15/18 = 3*5 /3*6 = 5/6
25/30 = 5*5 /5*6 = 5/6

But what's the 13/14 :(. You can't simplify it to 5/6 or something else.

Toretto has 7 cars and Brian has 3 cars. Rome has p more than the product of Toretto and Brian's cars. Write an expression for t

Minchanka [31]

Answer:

(7 x 3) + p

Explanations:

The number of cars Toretto has = 7

The number of cars Brian has = 3

The product of Toretto and Brian Cars = 7 x 3

The product of Toretto and Brian Cars = 21

Rome has p cars more than the product of Toretto and Brian's cars

The expression for the number of cars Rome has will be:

Number of Rome's cars = (7 x 3) + p

which can also be simplified as 21 + p

Answer:

$y=4x^2-8x-4$

Step-by-step explanation:

<u>Quadratic Function</u>

The quadratic function can be expressed in the following form:

$y=a(x-x_1)(x-x_2)$

Where a is a real number different from 0, and x1, x2 are the roots or zeroes of the function.

From the conditions stated in the problem, we know

x_1=1+\sqrt{2}, \ x_1=1-\sqrt{2}

Substitute in the general formula above:

$y=a[x-(1+\sqrt{2})][x-(1-\sqrt{2})]$

Operate the indicated product

$y=a(x^2-2x-1)$

To find the value of a, we use the y-intercept which is the value of y when x=0, thus

$y=a(0^2-2(0)-1)=-4$

It follows that

$a=4$

Thus, the required quadratic function is

$y=4(x^2-2x-1)$

Or, equivalently

$\boxed{y=4x^2-8x-4}$
