Step-by-step explanation:
2 : 3 = 6 : x ,
Ratio can be written as
2*3 = 6, we multiply top and bottom of fraction by 3
So value of x=9
4 : 7 = x : 42 ,
7*6 = 42, we multiply top and bottom of fraction by 6
So value of x=24
2x : 48 = 3 : 12,
\frac{3}{12}[/tex] =
2x= 12, so x= 6
12 : 15 = x : 20
,
we multiply top and bottom by 4/3

So value of x=16
-36-8 = -44
-36+(-8) = -44
third option
Your answer would be 2.93.
19 is the answer since 2 to the 2nd power is 4 5×4=20 -1 to the 2nd power is -1
20-1=19
