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

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 :)

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
