Let X = the number of months.
You need to multiply $70 by the number of months (x) which is written as 70x. You then need to add that to the initial deposit of $450.
The equation is:
Total = 70x + 450
Answer:
-x^2 +x
Step-by-step explanation:
f(x) = 1-x^2
g(x) = 1 - x
f(x) - g(x) = 1-x^2 - (1 - x )
Distribute the minus sign
= 1-x^2 -1 +x
Combine like terms
= -x^2 +x
154cm squared this is the only right answer
