145+67=212 One other way to solve it is to solve it is you subtract.
The perimeter of the rectangle is given by the formulae,

Where

is the length and

is the width of the rectangle.
Now let us substitute into the formula,


The above expression corresponds to option
F.
Now when we expand the bracket, we obtain,

This also corresponds to option A.
The correct answers are
Answer:
f(4) = 12.2
Step-by-step explanation:
we are given that x = 4, plug in 4 into the equation
f(4) = 5(1+0.25)^(4)
f(4) = 5(1.25)^(4)
raise 1.25 to the 4th, which is equal to 2.44
f(4) = 5(2.44)
f(4) = 12.2
