Answer:
144A+3AC
Step-by-step explanation:
I think you provided half of the problem. Because this does not make sense to any problem I can think of.
The answer is 23 because you would substitute in the 4 for the X and multiply 5 times 4 = 20 then add 20 plus 3 and you get 23
1 = 1 x 10 exponent 0
27.5 = 2.75 x 10 exponent 1
Just write all of that but instead of in the box between each statement and reason write if then
