The total cost of Anja’s trip to the dentist was $628.35. She paid a flat fee of $89.95 which included the checkup and cleaning

and then had 4 cavities filled, each of which cost the same amount. Which shows the correct equation and value of x, the cost of each cavity filling?
4 x + 89.95 = 628.35; x = 134 dollars and 60 cents
4 (89.95) + x = 628.35; x = 268 dollars and 55 cents
4 x + 89.95 = 628.35; x = 179 dollars and 58 cents
4 (89.95) + x = 628.35; x = 538 dollars and 40 cents

What is the area?<br> 4.6 yd<br> 7.7 yd
mario62 [17]

Answer:

A = 35.42 yd²

Step-by-step explanation:

We need to find the area if the dimensions are given as 4.6 yd  and 7.7 yd.

The area of a rectangle shaped figure is given by :

A = lb

Where

l is length and b is the breadth

So, put all the values,

A = (4.6)(7.7)

= 35.42 yd²

So, the area of the figure is equal to 35.42 yd².

<h3>What is Discriminant Formula?</h3>

The discriminant formula is used to determine the nature of the roots of a quadratic equation. The discriminant of a quadratic equationax^{2} +bx+c=0 is D =b^{2} -4ac

If D > 0, then the equation has two real distinct roots.

If D = 0, then the equation has only one real root.

Given that: Area\; of \;walkway,\; a(w)\;= 4w^{2} + 100 w

also, area of walkaway = 464 square feet.

So, 4w^{2} + 100 w =464

     4w^{2} + 100 w -464=0

Using Discriminant method,

a=4, b=100, c=-464

w= \frac{-b\pm\sqrt{b^{2}-4ac} }{2a}

w= \frac{-100\pm\sqrt{(100)^{2}-4*4*(-464)} }{2*4}

w= \frac{-100\pm\sqrt{17424} }{8}

So, w_1= \frac{-100+\sqrt{17424} }{8} \;\;\;\; w_2= \frac{-100-\sqrt{17424} }{8}

w_1= \frac{-100+132 }{8} \;\;\;\; w_2= \frac{-100-132}{8}

w_1 = 4 \;\;\;\; and \;\;\; w_2= -29

Hence the width of the walkaway be 4 feet.
