Suppose 400 dollars is invested in a savings account at interest rate i, compounded annually for 2 years. the amount A in the account after 2 years is given by A=400(1+r)^2. find an equivalent expression for A by squaring (1+r) A=400(1+r)^2 =

is the answer A  =  400 r^ 2  +  800 r  +  400

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

b
