Read the statement. Doubling the dimensions of a rectangle increases the area by a factor of 4.
If p represents doubling the dimensions of a rectangle and a represents the area increasing by a factor of 4, which
are true? Select two options.
Op q represents the original conditional statement.
~p~ ~q represents the inverse of the original conditional statement.
Oqp represents the original conditional statement.
0~~ ~p represents the converse of the original conditional statement
Op~q represents the contrapositive of the original conditional statement.

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
