<u>Answer:</u>
8x+ 6 is the translated mathematical expression.
<u>Step-by-step explanation:</u>
We are given the following English expression which are to translate into a mathematical expression:
<em>'The sum of 6 and the product of 8 and x” into a mathematical expression'</em>
Translating it in small chunks:
1. the sum of 6 ---> +6
2. product of 8 and x ---> 8x
Therefore, combining these we get the mathematical expression 8x + 6
They are the opposites of each other
(-13.2)+8.1=-5.1
13.2+(-8.1)=5.1
