Write and solve a quadratic equation for the situation below. Choose the answer that has both an equation that correctly models
Klio2033 [76]
Okay so the area of a rectangle x by y with a border of width b will be:

A=(x+2b)(y+2b)

A=xy+2bx+2by+4b^2  we are told that A=320, x=11, and y=15 so now we have:

320=165+22x+30x+4x^2, now I am using x as the border width...

4x^2+55x+165=320  is the equation that they listed..

...

4x^2+55x-155=0  using the quadratic formula for efficiency...

x=(-55±√5505)/8  since x>0

x≈2.399  which for some unknown (incorrect) reason they rounded to

x=2.5

So in short, your answer is a)

Solve the following inequalities and give the solutions in both set and interval notations.
andrew11 [14]

Given:

The inequality is

-\dfrac{x}{8}+\dfrac{8}{3}\geq 3

To find:

The solution for the given inequality in both set and interval notations.

Solution:

We have,

-\dfrac{x}{8}+\dfrac{8}{3}\geq 3

It can be written as

-\dfrac{x}{8}\geq 3-\dfrac{8}{3}

-\dfrac{x}{8}\geq \dfrac{9-8}{3}

-\dfrac{x}{8}\geq \dfrac{1}{3}

Multiply both sides by -8 and change the inequality sign.

x\leq -\dfrac{8}{3}

It means all the values of x which are less than or equal to -\dfrac{8}{3} are included in the solution set.

Set notation is \{x|x\leq -\dfrac{8}{3}\}.

Interval notation is  \left(-\infty,-\dfrac{8}{3}\right ].
