Can someone please answer this question I need it today answer it correctly please and show work show work please answer it numbers 24 and 22

Answer to 24 is A 0.3 d

Answer to 22 is D Negative number but may not be rational

Step-by-step explanation:

To get a 30% discount the multiplier is 0.7. Everything else gets to 0.7 is some way.

The other one m is more than 0 and n is more than 0. This means that one of the number could be a number that not rational. It has to be a negative because n has to be higher than 0 meaning you wouldnt be able to divide by a negative number which is the only way to make it positive

24) A

22) B

Step-by-step explanation:

24)

Original Price: d      

Sale: 30%    

A sale means that a value is subtracted from the original price

d - 30% = 0.7d

All options given:

A) 0.3d

B) 0.7d

C) d - 0.3d = 0.7d

D) (1.0 - 0.3)d = 0.7(d) = 0.7d

All of these options are equal to the price after the sale, except A.

A is the answer to question 24

22)  m > 0, n > 0    Use an example to represent m and n

m = 1, n = 2

= = -0.5

-0.5 is a rational, negative number

The answer to question 22 is B

Hope this helps :)

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
