Answer:

The correct answer is "x = 4" and "x = -12".

Step-by-step explanation:

The given equation is:

⇒  x^2+8x-30=18

On subtracting "18" from both sides, we get

⇒  x^2+8x-30-18=18-18

⇒  x^2+8x-48=0

On applying factorization, we get

⇒  x^2+12x-4x-48=0

On taking common, we get

⇒  x(x+12)-4(x+12)=0  

⇒  (x-4)(x+12)=0

⇒                 x-4=0

                          x=4

or,

⇒               x+12=0

                         x=-12

arthur wants to buy an item that costs p dollars before tax. using a 6% sales tax rate, write two different expressions that rep
Mkey [24]

For this case we have the following variable:

p: cost of the item that Arthur wants to buy before tax

The expression for the 6% tax is given by:

\frac{6}{100} p

Or equivalently:

0.06p

Therefore, two different expressions for the total cost are:

Expression 1:

p + \frac{6}{100} p

Expression 2:

p + 0.06p

To prove that they are equal, suppose that the item costs $ 100:

Expression 1:

p + \frac{6}{100} p

100+ \frac{6}{100} 100

100 + 6

106

Expression 2:

p + 0.06p

100 + 0.06 (100)

100 + 6

106

Since the cost is the same, then the expressions are the same.

Answer:

Two different expressions that model the problem are:

p + \frac{6}{100} p

p + 0.06p
