Option C
20x - 2(4x - 18) is not equivalent to given expression -12x + 36
Solution:
Given expression is:
-12x + 36
We have to find out the expressions that are not equivalent
Let us check the options one by one
Option ACombine the like terms
Add the like terms and add the constants
Thus this expression is equivalent to given expression
Option BBy distributive property we can say,
a(b + c) = ab + bc
Thus this expression is equivalent to given expression
Option CSimilarly, using distributive property,
But 12x + 36 is not equivalent to given expression -12x + 36
Option DSimilarly, using distributive property,
Thus this expression is equivalent to given expression
