Answer:

142.5

Explanation:

g = 0.6

First plug in the value of g, which is 0.6, into the problem⤵⤵⤵

400(0.6)^2 - 0.9 ÷ (0.6)

Remember PEMDAS

First off 0.6^2 is the same as 0.6 × 0.6 which is 0.36 .

Next multiply 400 and 0.36 to get 144 .

Then divide 0.9 by 0.6 to get 1.5 .

Lastly subtract 1.5 from 144 to get 142.5 .

This took me a while, because I was confusing myself a little, but I finally got it done. Here you go, hope this helps :)
