Which expression shows 27 + 36 as the product of their greatest common factor and the sum of two whole numbers with no common factor? a. 9(3+4)9(3+4) b.9(4+5)9(4+5) c.7(4+5)7(4+5) d.
7(3+6)7(3+6)

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
