Q: Buy one, get the second half price!<br>Find the percentage reduction of this special offer.​
Oliga [24]

Answer:

get 1 … what? free? half-price? something else?

Let x= price of 1 item

Then 3x= price of 3 items

Buy 2 , get 1 free

Total cost =2x

Discount =3x−2x=x

Discount percentage =x/(3x)=0.333…=3313%

Buy 2 , get 1 half price

Total cost =2x+0.5x=2.5x

Discount =3x−2.5x=0.5x

Discount percentage =0.5x/(3x)=0.1666…=1623%

A rectangle has a length of 25x^3 and a width of 5x^2. Fkns the area.​
Anna11 [10]

Answer:

Step-by-step explanation:

I hope you want the area.

Area = L * W

L = 24x^3

W = 5x^2

Area = 24x^3 * 5x^2

Area = 120 * x^(3 + 2)

Area = 120 * x^5

Note

When you multiply numbers or letters that have powers, if the base for both of them is the same, the powers are added.

The above answer is an example x^2 * x ^3 are letters (x) that are raised to the 2nd power and the 3rd power. You add the powers.

Numbers can do the same thing

  • 2^5 * 2^3 = 2^8
  • 2*8 = 256
  • 2^5 = 64
  • 2^3 = 8

64 * 8 = 256
