Question

Evaluate the following expressions by substituting s = 20 and t = 6

s - 0.2t2
12.5
10.8
12.8
18.8

Answer 1

The answer will be the 3rd option, 12.8

Explanation:

I'm gonna assume that since you copy and pasted the question, the equation is actually s - 0.2t^2

Now we just need to substitute the values with their respective ones.

20 - 0.2(6)^2

Now we just have to solve :)

20 - 0.2(6)^2

= 12.8

So the answer will be the 3rd option, 12.8

Hope this helped! :D
