Answer:
No they are not equivalent
Step-by-step explanation:
The given expressions are r + 4(2 + r) – 12, and 8 + 2r – 6
Let us first put r= 2 in the above expression
2+4(2+2)-12= 6
and 8+2(2)-6 = 6
Now let us put r=5 in the above two expressions
5+4(2+5)-12 = 21
similarly, 8+2(5)-6 = 12
Clearly, the two expressions are not equivalent when we put r=2 and r=5 as the values coming are different.
