tina solved a quadratic equation and found the solution to be -3/2 and 6 which of the following is equivalent to the quadratic e

Bond [772]

Answer:

$x^2-\dfrac{9}{2}x-9=0$

Step-by-step explanation:

The solutions of a quadratic equation are :

x = -3/2 and x = 6

or we can write it as :

$x+\dfrac{3}{2}=0\ and\ x-6=0\\\\(x+\dfrac{3}{2})(x-6)=0$

Multiplying both values,

$(x+\dfrac{3}{2})(x-6)=0\\\\x^2-6x+\dfrac{3}{2}x-9=0\\\\x^2-\dfrac{9}{2}x-9=0$

Hence, the required quadratic equation is $x^2-\dfrac{9}{2}x-9=0$ .

A neighborhood development that is 4 acres is to be divided into 2/3 acre lots. How many lots can be created?

mihalych1998 [28]

6 lots can be created

<em><u>Solution:</u></em>

Given that neighborhood development that is 4 acres is to be divided into $\frac{2}{3}$ acre lots

To find: number of lots created

From given information,

Total acres = 4

one lot = $\frac{2}{3} \text{ acres }$

So number of lots created can be found by dividing the total acres by acre of 1 lot

<em><u>Thus the formula is:</u></em>

$\text{ Number of lots } = \frac{\text{ total acres }}{\text{ acre of 1 lot }}$

<em><u>Substituting the values we get,</u></em>

$\text{Number of lots } = \frac{4}{\frac{2}{3}} = 4 \times \frac{3}{2} = 6$

Thus 6 lots can be created

A rectangular flower garden has an area of 75 square feet. It is 15 feet long. How wide is the garden? *

nlexa [21]

A. 5 feet

To find the area of a rectangle, multiply length by width. Since the length is 15, you divide 75 by 15, so the width would be 5 feet.
