The length of the rectangle is 3 cm

<h3>Applications of Quadratic equations</h3>

From the question, we are to determine the value of the length of the rectangle

To find the length of the rectangle, we will determine the value of x in the given equation

The given equation is

x^{2} + 5x =24

This can be written as

x^{2} +5x -24 =0

Factorizing

x^{2} +8x - 3x -24 = 0

x(x+8) -3(x+8)=0

(x-3)(x+8)=0

Then,

x-3 = 0 OR x + 8 = 0

x = 3 OR x = -8

Since, the length of the rectangle cannot be negative, the value of x is 3.

Hence, the length of the rectangle is 3 cm.

aivan3 [116]

<u>ANSWER: </u>

The total cost of the skate board is $74.61.

<u>SOLUTION: </u>

Given, Luis wants to buy a skateboard that usually sells for $79.99. all merchandise is discounted by 12%. luis has to pay a state sales tax of 6.75%.  

We need to find what is the total cost of the skateboard.

Final cost is nothing but original amount subtracted by discount and added with tax.

final cost = original cost – discount + sales tax

Original cost = $79.99

Discount = 12% of original cost

\begin{array}{l}{=12 \% \times 79.99} \\\\ {=\frac{12}{100} \times 79.99} \\\\ {=\frac{959.88}{100}} \\\\ {=9.5988}\end{array}

discount is $9.6 approximately

Sales tax = 6% of cost after discounting

\begin{array}{l}{=6 \% \times \text { (original cost - discount) }} \\\\ {=\frac{6}{100} \times(79.99-9.6)} \\\\ {=\frac{6}{100} \times(70.39)} \\\\ {=\frac{422.34}{100}} \\\\ {=4.2234}\end{array}

Sales tax is $4.22 approximately

Now, final cost = 79.99 – 9.6 + 4.22

= 84.21 - 9.6

= 74.61

Hence, the total cost of the skate board is $74.61
