If you mean: cd which means c*d then it is 3.5*12.8 = 44.8
Technically is can be anything you want it to be since you did not equate this expression to any value.
Replace each variable in the expression by its value and then find the value of the expression.
Take the value of each variable in the expression and replace the variable by its value. Then do the math!
The answer will depend on the expression - which is not given!
no
It is 138.
If there are d $1 bills their value is $1 × d, or d dollars.Each $5 bills is worth 5 times as much so if there are f bills their value is $5 × f, or 5f dollars.Thus the expression for the total would be d + 5f dollars.

If you mean: cd which means c*d then it is 3.5*12.8 = 44.8
c + d = 17.5 c - d = 12.3 c x d = 38.74 c/d = 5.73076923
36.5 is not an exponential expression! Its value is 36.536.5 is not an exponential expression! Its value is 36.536.5 is not an exponential expression! Its value is 36.536.5 is not an exponential expression! Its value is 36.5

to find the value of an expression, you need to
An equivalent expression.
You evaluate the expression !! :)
